Well, following instructions at the GP2X wiki, I first got TCP/IP over USB going and was able to telnet and ftp onto the GP2X. I had to add a few modules to my desktop's kernel like USB->USB Gadet Support -> Ethernet Gadget, and USB -> Network Adapters -> Host for RNDIS. Then it was as easy as turning it on on the GP2X and
ifconfig usb0 up 10.1.0.1
on the desktop and we were a go.
Next I setup a development environment and was able to compile a simple hello world program,
/usr/local/devkitPro/devkitGP2X/bin/gcc -o hello hello.c
ftp it to the GP2X, and run it there. It's a start.
