:-). [BTW what is status of powernow-k8? is it pending or does it need

Will not first change in thermal system unthrottle it for me, behind
my back?

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 ;-)].
