As of BTest-3 (and possibly BTest-2-2), the Touch pad should periodically recalibrate itself automatically.
However, Shiga-san says ideally, the touchpad needs recalibration whenever the XO-1 goes onto, or off of external power source. A command to the touchpad was added to enable this recalibration to the later touchpads.
The touchpad might also need recalibration after long sleep, but as we're not removing power, I don't see why this would be true.
Ideally, the embedded controller should trigger this recalibration, as otherwise, I can see it as a (not very serious) denial of service problem if this is possible from user space.
