Thanks for the detailed information everyone. The first time I tested this
I was under the impression that it indeed had an influence on the produced
heat of the CPU. I did a quick test this morning and of course you are
right, there is no change at all. 

This is a good thing though, since it gives me an excuse to upgrade this
machine to a C2D. :)
For the time being I will just disable the cpufreq stuff since it really
does not make a difference in my case.

Kind regards,
Michael
