Hi Detlev
Something seems wrong with your recommended cat command:

sna at WS222:~$ cat /proc/acpi/processor/CPU0/power
cat: /proc/acpi/processor/CPU0/power: No such file or directory
sna at WS222:~$

Or are some some extra (ACPI) installations needed ??

An IBM Thinkpad T30 with a 2.4MHz CPU runs quite hot here ...
... even with the A/C on the whole day !!

IBM Services changed the fan and its exhausts already and it still seems
quite hot always in the upper 60 degrees Celsius !? The top surface of
the KBD is very warm too !!!

Interested to hear more about how to recognize and solve this
problem. ;-)
