The contents of /proc/bus/input/devices would be handy.

No, but you can probably use an existing touchscreen or touchpad driver.
The evtouch driver may be more mature at the moment, specificly in that
it supports some level of calibration, screen rotation, and tap handling
if the kernel driver doesn't.
xf86-input-evdev should gain all of those abilities over the next month
or two, but for a touchscreen now you might want to try evtouch first.
Hope this helps.
