ok, that's good news then (I'll need to check the kernel driver to be sure
though)

that is acceptable. the kernel buffers values, so if the major axis does not
change then no events will be sent. and since the axis describes the size of
the touchpoint it does not change too much while the finger pressure remains
the same. Can you confirm though that the ABS_MT_TOUCH_MAJOR event comes as
soon as you physically touch the touchpad? To detect this we only need one
event, after that it doesn't matter (though it'd be interesting to see if it
goes back to 0 or so on physical release)
