So, does that mean that the power-management i use is not including
voltage-adjustments and that voltage-adjustments are supposed to be used
(as in part of the whole power-management thing for this cpu and also
been done in windows for example)?

I have a ipw3945 and have set the power-management with "iwpriv eth1
set_power 7" which is confirmed by iwconfig.

Yes it is a random number, seems to get higher on high clock/load, is
that alright?
Im also not familiar with those active states (mostly in C2) i have to
check that out.
