From another hand, my daily driver had rare and anoyed bug when touchpad is
a kind of "stuck" and ignores clicks. Usually to "fix" that I need to use
multitouch click.

Since I start run your diff on this machine, I haven't encountered it.

Probably you had fixed it as side effect.

So, I'd like to OK it and suggest to go it in and see reports in bugs@ in
the case if it brokes somehting.
