Heh :)

More questions: What about the resume stuff? IIRC the idea was that the 
accellerometers could be programmed to wake up on certain gestures^wevents -- 
is that still possible and if so, how?

Well, properly dealing with accellerometers is a complex thing. I have added 
an entry to the GSoC 2008 list of ideas. At the end of the day, you want 
gestures, not data. Towards this we will probably need to adopt something 
like tslib does.

:M:
