Comment(by dsaxena):

 OK, did a bunch more packet dumping, looking at the Synaptics docs, and
 research and determined that we are getting proper pointer data from the
 device. The reason we were seeing the jumpiness is that by design the TP
 sends us data once a finger gets fairly close to it and the Z value in the
 packets tells us how close we are. Since we were using the standard X
 mouse driver, it was not taking this into account. I installed the
 xorg-x11-drv-synaptics package and hacked my Xorg.conf to use this driver
 instead and the sensitivity works OK and I can use some of the Synaptics
 features like scrolling with my finger on the right edge of the screen
 (very nice with browse!). My current Xorg.conf is somewhat of a hack and I
 need to create one that will work on both existing and new TP. I'll open
 some bugs to track that and bring in the synaptics package into our
 builds.

 Anyyays, I still see the dropped key down events. I tried changing the
 packet rate on the mouse to 40/s and that does not help. Wad, do we have a
 a developer contact at Synaptics? I'd be nice to be able to just ask
 someone "have you seen this before and if so what usually is the problem?"
