Hi there,

I am working on a vaio laptop pcg-fr415b, using fc5 (see result of cat 
/proc/cpuinfo above).
Since it is quite noisy I allowed cpuspeed at startup and this improved 
the situation a little bit.
Still cpufreq-info (see details above -in french, but you can guess) gives
hardware limits : 2.10 GHz - 2.80 GHz
Is there any hope to go below 2.10 GHz and if yes, how ?

Thanks,

Niels
