Yeah, that one is really weird ;)

I noticed that lately, Apple changed Darwin trackpad code so that instead of
reading the 8 bytes of the config register, changing them, and writing them
back, it always write hard coded default values (doesn't read).

So I guess there might be a problem when reading the ADB datas from the
trackpad (timing issue) and rewriting those bogus datas cause the trackpad
to die.

I'll do some more experiments asap.

Ben.
