Hi Norberto,

your temperature values are a little bit too high. On my Notebook
(model name      : Intel(R) Pentium(R) M processor 1.73GHz) the CPU is  
at between 50°C - 60°C when I use normal desktop applications and up  
to 80°C when I compile something.
You could open your case and look if there's dust in the airflow so  
the fans cannot blow out all the hot air.
I only use the powerd with "-a adaptive -b adaptive" flags. There  
should be no need for the cpufreq module.

Lars
