Maybe vibrator device will be needed after all?
1) it is getting very common
2) timed-gpio model makes more sense for vibrators -- send 200msec
pulse
3) normal triggers make little sense. 'vibrate when battery charges'
is cool hack, but
4) can vibrator motor survive running 24/7 ?
5) it is really force feedback; we have input handling for that. Is it
unusable?
