need help slack 12.2 and lifebook p1120 touchscreen


ok here's the issue...

i have a fujitsu lifebook p1120 that was previously running slack 12.
since the touchscreen is detected as a usb joystick, i used a program called joytouch (http://sifter.org/~simon/journal/20060413.html) to translate the input events which worked flawlessly.

i've now upgraded to slack 12.2, and the 2.27.7 kernel seems to be picking up the touchscreen right out the box. problem is the calibration is way off and i have no idea what driver it's attempting to use so i can enter the proper calibration in xorg.conf

on top of that if i try to just use joytouch, it seems to be fighting with the driver it's falling back on. taps are being read as double taps, cursor jumps around, etc...

so what i need help with is either finding the correct device and driver the kernel is trying to use so i can calibrate in xorg.conf (even though it's detected as a usb device, lsusb shows nothing), or disabling the device so that joytouch(either the driver or in X) will work properly. only reference i can find in dmesg is to hiddev, but unless i'm mistaken, disabling that will disable usb input device entirely.

relevant dmesg output
Code:
apanel: unknown device 11 found
usb 1-3: new low speed USB device using ohci_hcd and address 2
usb 1-3: configuration #1 chosen from 1 choice
