Yes, now the the machine runs at full speed I may add minor issues to my list.

I do not know any details, but under MacOS X someone managed to write a fancy program which stabilises a window (i.e. the window does not turn when you physically turn your laptop to the side). From his webpage I got the impression that it was not so difficult to figure out. There seem to be three sensors, two measuring the angle around the x and y axes (spanning the plane the keyboard is in) and the third measuring the acceleration in z direction. Maybe accessing the following devices in a sensible way may just work?
