I tried the mainline kernel on Oneiric but it didn't make the device show up in 
geisview. Also in Oneiric X started hanging
when I tried to make gestures, seemed like some kind of input/keyboard grab. i 
can still switch to text vc and
back, and kill the session with the SAK.

I now upgraded to Precise beta. This time geisview shows the device but
the hang bug is the same.

I get some stuff in Xorg.0.log, here's the part that comes when the bug occurs. 
I'm also attaching the entire Xorg.0.log file
for the session.
