Sorry, using the performance governor was my bad - I almost always swit=
ch to
performace manually because working on that computer with 800MHz ist ju=
st
painful.

I rebooted the machine to get some clean results and ran some CPU inten=
sive
calculations with matlab, the load was at 100% for quite some time and =
the
frequency did not change at all.
Temperature can't be the problem since the CPU temperature was reported=
 as
35=C2=B0C-40=C2=B0C (I checked), with the performance governor the temp=
erature will go
above 70=C2=B0C before the CPU slows down because of too high temperatu=
re.

I'll append the information you requested now.
Please also note the following:

# cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
2001000 0
2000000 0
1600000 0
1200000 0
800000 84859

Was done with ondemand governor enabled this time ;)
