I'd should not expect battery conservation *when cpu is idle*. If I'm moving windows in X, 0:7 limit will actually help. And it should allow battery to be drained further by limiting maximum amps eaten by CPU. [Ok, that's little evil, but being able to run for 30 minutes+ on 0% battery is nice ;-)].
