I found a webpage from which I downloaded the Zaurus driver for the PockeTop folding keyboard. At first, I got a little mad because according to Pocketop's page, you have to pay for drivers. Luckily I found the above page, which has a freely downloadable driver. However, I wasn't paying attention and didn't realize all the prerequisites, like Python and the VNC server. I might should have read the README before I got all excited.
