Yes, this is that correct one. I forget the name of this daemon.

Just to note /dev/freefall does not provide axes state, it just send
signal to process when interrupt is triggered. Process than park disk
heads.

Axes state are/were exported throw /dev/js* interface and those games
uses just js interface. I remember Tux Racer.

Interrupt on HP and Dell is triggered only when laptop fall is detected,
so games did not used it (hopefully!)
