yes, it is. Just use the ondemand governor.
I've noticed what looks like some work overloads using the ondemand
governor. I'm pretty sure it is normal but I can see (user feeling) when
the system loads the processor by intermittence. It is visible on some
compilations tasks and when playing flash videos and compared to the
performance governor. I'm still runing a 2.6.26 kernel.
of course there is a little difference. Performance is not a governor. It just
sets the cpu at always full speed. So it does not have any ramp up time - but
also blows away a lot of energy AND generates unnecessary heat.
