Sierra Wireless MC5725 on Debian Linux

When I started my new job I was given an HP Compaq 6910p as a work laptop, which came with a nice embedded 1xEVDO (Sierra Wireless MC5725) card that I could use to get online anywhere where there is a Verizon signal. Over the past week or so I've been migrating from Windows XP to Debian, and this was the last bit of hardware I needed working. Here are my notes on how to get it up and running:

Requirements:
Kernel 2.6.21 or newer with sierra module compiled or latest from http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=607
Device activated in Windows and powered on (disable turning power off in preferences)

Load the modules:
sudo modprobe usbserial vendor=0x03f0 product=0x211d
sudo modprobe sierra

Setup kppp:
Uncomment noauth in /etc/ppp/peers/kppp-options
Modem device: /dev/ttyUSB0
Flow Control: Hardware
Line termination CR
Connection Speed 921600
Phone Number: #777
Authentication: PAP/CHAP
Login ID: your_device_phone_number@vzw3g.com
Password: vzw

Automatically load modules in Debian:
edit /etc/modprobe.conf/usbserial and add:
options usbserial vendor=0x03f0 product=0x211d
edit /etc/modules and add:
sierra
