Hi Andrea, You have the same problem as me! The problem is inside /etc/cpuspeed.conf. You will find that the only driver listed there is PowerNow, so unless you are using a AMD processor, you will probably get the error you are seeing now. I have a Centrino CPU and tried to add speedstep_centrino, but that driver is missing too. Artu on this list said something about an ondemand governor which I will look into tomorrow morning.
