When I recieved my laptop last week, I had windows preinstalled on and before reinstalling a proper free system, I wanted to have a look to that feature, so I lauched the ibm HDAPS monitor. But to my mind precision is not really good, and when you roll your laptop twice or more the monitor forget its initial position and movements are only relative (may be a software issue, I don't know). But i love your idea ;)
