Yes, I was using powernowd (launched from console). Every governor I set, always use the maximum frequency available, careless of the work load.
I tried to replace speedstep_centrino module with acpi-cpufreq, but the problem remain the same. I can't understand why the userspace governor used by powernowd can make frequency scaling and those configured by me can't do it. Theoretically the manager ondemand would have to use the minimal frequency when the load of the cpu is near to 0%, right?
