You can find them by grepping for ABS_MT_ in the drivers/hid/ directory. hid-3m-pct, hid-magicmouse, hid-mosart, hid-ntrig, hid-quanta and hid-stratum all generate multitouch events. Most of them use standard HID report descriptors; however, hid-magicmouse has to translate input reports that don't have published descriptors. Depending on how the screen behaves, you'll probably want to look more at the other drivers than hid-magicmouse.
