I have a 700MHz iBook 2.2 and I wonder whether it scales the cpu frequency dynamically based on load and policy.

So static scaling seems to work. However, when I generate load in the powersave mode, the clock speed and bogomips count stay the same. The only difference I see is in the cpu temperature, which starts to climb very fast. Is this an indication of higher cpu speed? Or is it still clocked at 400MHz?
