I booted up the compaq desktop box ("xavier") on a ubuntu 9.04 live cd, 
but it doesn't look like it has a hard drive.  I was unable to find a hard 
drive that was of the right type (ATA) that I was sure was available, and 
it's a little too tedious for me to do development on a ramdisk platform.

Anyways, I got the calibration tool working using the touchscreen's RS232 
interface, so now we can make pretty pictures by drawing text "T"s around 
the scren.

Do we have a hard drive anywhere we can install on a machine with a db9 
serial port that I can continue trying to get the X driver working on?
