Re: [PATCH] Synaptics TouchPad driver for 2.5.70

Just as a idea for API. How about ABS_AREA or REL_AREA instead of
ABS_MISC. The idea is the pressure value returned should be about
the same if one presses hard with one finger or softly with a whole
hand. So to tell the difference between the two we can report the
pressure and the area over which it acted. Say in virtual reality
environment simulation poking a object hard with your finger would
have a very different effect than placing your hand lightly on the
object even tho they might register about the same pressure.
