Sorry, using the performance governor was my bad - I almost always switch to
performace manually because working on that computer with 800MHz ist just
painful.

I rebooted the machine to get some clean results and ran some CPU intensive
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°C-40°C (I checked), with the performance governor the temperature will go
above 70°C before the CPU slows down because of too high temperature.

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 ;)
