Okay, I don't know how I missed that -- thanks :-)
So, the 'usbtouchscreen' kernel only announces that it sends
BTN_TOUCH, which is indeed the only thing it sends. The problem is
that I can't just change how things work in the evdev X11 driver as
that will most likely cause problems for people with touchpads. So,
what is the proper solution? Should the touchscreens send a different
signal (e.g. BTN_LEFT or possibly a new one called BTN_SCREENTOUCH)?

P.S. Also CC'ing the list -- hope that's okay
