I figured out, that the preemptive-patch from
http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/v2.4/
is responsible for all the couters staying at [00000000]. With this
patch not applied 2.4.31 works as expected. So, this was my fault at
all. Sorry for bothering the list.

I'm afraid that I can't use 2.6 because of annoyances with the nvidia
X11-drivers. So I'm stuck to 2.4.
