It depends on what exactly you are calibrating. If it is only about 
sensor value range, evdev will adapt to what the kernel specifies in 
EVIOCGABS (ABS_X / ABS_Y). Should suffice in the usual case.

If there's more, well, it's really up to you. In-kernel means gpm stuff 
works too.

As for dev props, peter's post is everything non-code I saw yet:
