One other note:

> ABS_MT_TRACKING_ID, nt_rpt->finger_id);

I pulled the tracking id to conform to
	Documentation/input/multi-touch-protocol.txt
which states that unreliable tracking ids should not be passed to the user
space.  So unless you have done something to fix the broken tracking that I've
been seeing, we should leave it out for now.
