X's evdev driver is an X driver, not a kernel module.  lsmod shows kernel
modules.  Look in the X log file instead.

Use an InputClass section to match the device based on product or vendor name,
instead of on the device filename.  See the manual page for xorg.conf, and
refer to /proc/bus/input/devices for the ID strings for your touchscreen.
