however, i've found /hardware/ mouse acceleration to be a mistake.
at least some kvm eat or mangle these commands, which motiviated
me to consider the issue, and i don't see a reason why the kernel
shouldn't just do the acceleration (multiplication) itself. surely one
multiply should be of no concern on a 100Mhz+ computer.
:-)
the code's in the 9atom kernel, fwiw.
