[Beowulf] Powersave on Beowulf nodes

What is about using of powersaved (and dbus and HAL daemons) on 
Beowulf nodes ?

Currently I installed SuSE 10.3 where all the corresponding daemons 
are running (by default) at the runlevel=3. I simple added issuing of

powersave -f
at the end of booting. 

  /proc/acpi/thermal_zone/ is empty, and powersave can't give me 
temperature and FANs information. I don't see now any serious 
advantages of powersaved daemon using in "performance" mode (using 
performance scheme). 

We have many jobs in SGE at every time moment, and underload situation 
(where it's reasonable to decrease CPUs frequency) is not the our 
danger :-)  So I'm thinking about simple stopping of all the 
corresponding daemons.
