Okay, never mind, we were too quick in thinking everything was correct,
the parameters seem to be wrong. The touchpad is detected and seems to
work, but in 'synclient -m', you see that actually nothing happens.

Dmitry, do you know which parameters we need to tweak to fix this? Maybe
the 0xff, 0xff mask is wrong? Or the flags? Sorry, my knowledge ends here.

Been there, done that. I originally pushed a patch with this signature
about a month ago. It was applied, but then reverted because it didn't
work right. It seems there's a new protocol for these alps touchpads
that will need to be figured out first.
