Kernel 2.4 or 2.6? (Your Pi is running 3.6.) Monolithic XFree86? (Modular XOrg has been around for ages.) I'm sorry to say that unless you can find a driver package for a much newer environment, you're not likely to get this thing to work.

Can you plug the thing in to your Pi and then issue the "lsusb" command? Maybe its VID and PID are nowadays supported by one of the mainstream Linux USB touchscreen drivers.
