Hello Michal,
here are the results of a few more tests I did.
First, I wiped out my configuration, just to make sure it's not a problem
with it. Then I started gsynaptics and disabled tapping (it's the only
setting I use). I started gsynaptics-init and the touchpad froze.
Here is the result of the strace:

I hope you can understand something out of it.
Now back to another bugreport, as 2.6.25-2 does not seem to wirk nicely with
the touchpad...
