I must just repeat what you say. Of course, I cannot say how cooler or
how much lower on electricity does this run, but my 3GHz P4 also
dropped to 375MHz. And it was painful.
I hand-adjusted the minimum to 1GHz, but still... I'm unsure whether
to leave the ondemand governor active, as it might just never go back
to 3GHz on its own.
