Definitely not. I also have a strange problem since then: the mouse is 
only sporadically recognized, on every second boot or so.

Hm, that could be a good sign, couldn't it? Maybe we just have some too 
strong timeouts, missing snoozes(), etc. that the debug output is 
accidently correcting?

Oh, that problem again. Okay, than it's probably still not a good sign.

This shouldn't cause problems (if the driver is working correctly), but 
it could very well trigger the symptoms we see.

I didn't think keyboard controllers are that annoying.
I have some local changes on my keyboard.c as well, maybe they can 
improve the situation (they are already quite old, but there must have 
been a reason for playing with it).
