Thats for pointing me in the right direction.  I decided to try openembedded real quick because I found that the tsc2003 module is included by default.  Also, I've been able to get wifi working.  I still have 2 problems though
1. Wifi doesn't start on boot.  eth0 starts fine, but I have to run /etc/init.d/networking restart.  I want to say that this is a problem with wpa2 and wpa_supplicant, and the order that modules are loaded at startup.  or something like that.  Anybody else have this problem? 

This is the output at boot

udhcpc (v1.2.1) started
udhcpc[574]: udhcpc (v1.2.1) started

2.  Can I use the tsc2003 driver to get to the a2d ports? When I add the tsc2003 mod I get this:

root@gumstix-custom-verdex:~$ modprobe tsc2003
tsc2003 i2c touch screen controller

Is anybody else using the a2d ports?  If so, how are you getting the info?  Direct from i2c?

In this case, the precompiled i2c is not compatible with the version
of software running on your gumstix. You'll need to build a copy of
the i2c program designed for use with the version of buildroot that
you're running on the gumstix.

If you download the robostix tree by doing the following

cd gumstix-buildroot
cd ..
svn co http://svn.gumstix.com/gumstix-buildroot/branches/projects/robostix
robostix
cd robostix/gumstix/i2c
make

This should compile and build i2c, assuming you've already built
buildroot in the gumstix-buildroot directory.
