I have heard that there is a demand for this kind of information so I
figured I would post it here as well.
The original article is posted here in the Gentoo forums:

This how-to will discuss how to get EVDO on Gentoo Linux. Specifically
Verizon EVDO using the Keyocera KPC650 EVDO PCMCIA card.
Most if not all EVDO PCMCIA cards are just serial modems with usb-serial
hardware. So they basically just show up as USB devices. They could have
just been serial devices but I guess it's easier in windows to make it a
USB device that converts to/from serial, maybe it's easier to write
drivers for or easier to work with. But it makes it relatively easy for us
to support it in Linux.
On a personal note, I remember being a geek kid around 10 or 12 owning my
dad's second hand laptop and thinking I was the coolest! Well I saw in
some movie, tv or magazine cellular modems. I thought how cool would that
be, to have Internet anywhere. Throughout the years anywhere/anytime
Internet was obtainable for the common man but dialing up via cell cost
way too much for me in my teens (I'm 22 now and have a full time job). So
when I got my job, and Verizon reduced the price of EVDO from $80 to $60 I
instantly went out and bought the service. My childhood dream came true.
Wow I'm a geek.
Anyways....

1. Add usb-serial generic driver support in the kernel.
2. Patch your kernel
3. Add ppp to your kernel and emerge ppp
4. create ppp scripts
5. Reboot and insert PCMCIA card
6. Calling and connecting
Important Notes
Make sure to activate your EVDO PCMCIA card using the included Windows
software. It is required! Borrow someone's laptop like I did. Once this is
done and tested in Windows, it will be recognized by the EVDO network no
matter what OS its in.
Disclaimer
This guide is as complete as I can make it. I will probably add and
correct some things as time goes on, or as people add them. If i have made
any errors or any mistakes please let me know and feel free to e-mail
me/PM me for help. Making how-to's more accurate helps everyone.
1. Add usb-serial generic driver support in the kernel.
Code:
Symbol: USB_SERIAL_GENERIC [=y]
Prompt: USB Generic Serial Driver
Defined at drivers/usb/serial/Kconfig:46
Depends on: USB && USB_SERIAL
Location:
-] Device Drivers
-] USB support
-] USB Serial Converter support
-] USB Serial Converter support (USB_SERIAL [=m])
Important Note
Add usbserial vendor=0x0c88 product=0x17da maxSize=2048 to your
/etc/modules.autoload.d/kernel-2.6. Note the maxSize= parameter, this was
added by the patch. The vendor/product ID's will differ if your using a
card other than the Keyocera KPC650. Just put in your appropriate ID's for
your hardware.
2. Patch your kernel
See my other thread http://forums.gentoo.org/viewtopic-p-3067617.html#3067617 for the patch and more info.
3. Add ppp to your kernel and emerge ppp
Add PPP support:
Code:
Symbol: PPP [=m]
Prompt: PPP (point-to-point protocol) support
Defined at drivers/net/Kconfig:2426
Depends on: NETDEVICES
Location:
-] Device Drivers
-] Network device support
-] Network device support (NETDEVICES [=y])
Add PPP support for async serial ports:
Code:
Symbol: PPP_ASYNC [=m]
Prompt: PPP support for async serial ports
Defined at drivers/net/Kconfig:2482
Depends on: NETDEVICES && PPP
Location:
-] Device Drivers
-] Network device support
-] Network device support (NETDEVICES [=y])
-] PPP (point-to-point protocol) support (PPP [=m])
Selects: CRC_CCITT
Emerge ppp:
Code:
emerge ppp
Important Note
Add ppp_async to your /etc/modules.autoload.d/kernel-2.6 and it should
auto-load the modules dependencies on reboot. Or just modprobe it for now.
4. create ppp scripts
Since I use the Verizon EVDO service they will be named as such. Feel free
to rename. in /etc/ppp/peers/ we will create three scripts: verizon
verizon-connect verizon-disconnect
verizon
Code:
#the USB serial device of the EVDO PCMCIA card.
tts/USB0
#your login information
user YOUR_TEN_DIDGET_CELL_PHONE_NUMBER@vzw3g.com
230400 # speed
#debug
defaultroute # use the cellular network for the default route
usepeerdns # use the DNS servers from the remote network
-detach # keep pppd in the foreground
crtscts # hardware flow control
#lock # lock the serial port
noauth # don't expect the modem to authenticate itself
connect "/usr/sbin/chat -v -f /etc/ppp/peers/verizon-connect"
disconnect "/usr/sbin/chat -v -f /etc/ppp/peers/verizon-disconnect"
verizon-connect
Code:
#time out is 20 because sometimes the card takes a little while to
initialize.
TIMEOUT 20
ABORT 'BUSY'
ABORT 'NO ANSWER'
ABORT 'NO CARRIER'
SAY 'Starting Verizonn'
'' 'AT'
'OK' 'ATQ0V1E0'
'OK' 'ATZ'TIMEOUT 20
ABORT 'BUSY'
ABORT 'NO ANSWER'
ABORT 'NO CARRIER'
SAY 'Starting Verizonn'
'' 'AT'
'OK' 'ATQ0V1E0'
'OK' 'ATZ'
'OK' 'AT&F'
# Dial the number
SAY 'Connecting...n'
'OK' 'ATDT#777'
CONNECT CLIENT
'OK' 'AT&F'
# Dial the number
SAY 'Connecting...n'
'OK' 'ATDT#777'
CONNECT CLIENT
verizon-disconnect
Code:
"" "K"
"" "+++ATH0"
SAY "Disconnected from Verizon."
5. Reboot and insert PCMCIA card
Now you should reboot with your new patched kernel, with your modules auto-loading.
Insert your PCMCIA card and look at your dmesg output, it should be similar to mine:
Code:
pccard: CardBus card inserted into slot 0
PCI: Enabling device 0000:04:00.0 (0000 -] 0002)
ACPI: PCI Interrupt 0000:04:00.0[A] -] GSI 19 (level, low) -] IRQ 17
PCI: Setting latency timer of device 0000:04:00.0 to 64
ohci_hcd 0000:04:00.0: OHCI Host Controller
ohci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 6
ohci_hcd 0000:04:00.0: irq 17, io mem 0x42000000
hub 6-0:1.0: USB hub found
hub 6-0:1.0: 1 port detected
PCI: Enabling device 0000:04:00.1 (0000 -] 0002)
ACPI: PCI Interrupt 0000:04:00.1 -] GSI 19 (level, low) -] IRQ 17
PCI: Setting latency timer of device 0000:04:00.1 to 64
ohci_hcd 0000:04:00.1: OHCI Host Controller
ohci_hcd 0000:04:00.1: new USB bus registered, assigned bus number 7
ohci_hcd 0000:04:00.1: irq 17, io mem 0x42001000
hub 7-0:1.0: USB hub found
hub 7-0:1.0: 1 port detected
usb 6-1: new full speed USB device using ohci_hcd and address 2
usbserial_generic 6-1:1.0: generic converter detected
usb 6-1: generic converter now attached to ttyUSB0
usbserial_generic 6-1:1.1: generic converter detected
usb 6-1: generic converter now attached to ttyUSB1
Important Note
ttyUSB0 is the device we put in the PPP scripts. If you have other
usb-serial devices this will be different (maybe USB1 or USB2 etc).
6. Calling and connecting
As root just type
Code:
pppd call verizon
and you should connect to the EVDO service.
That should be it!
I expect there to be some error or mistake on my part above. If i have not
explained something clearly or left something out, contact me.
