Are you aware of http://bitmath.org/code/multitouch/? The driver was developed
to address very similar issues on the macbook trackpads.

Also addressed in that project. What I am hoping to see, eventually, is code
similar to the core of the multitouch project in something like ginn. This would
exercise the whole utouch stack in an extensible way, and finally make
multitouch trackpads work the way they are supposed to.
