This is quite interesting, as there is only one function/macro, which
seems to be messing up things -- I don't know much (hardly anything)
aboout that hardwarestuff, but I'll have a look at i8042_command as
soon as I find the time. At least it's a start...

It works, so this seems to be the exactly same issue. I only tested
with the code before the point above, I'll do further testings at the
weekend, but I'm quite optimistic, that you found the point of
failure. Thanks!

don't worry, lots o'kernel here... ;-)
