Hmm, a few hours later and one s2ram / resume cycle in between, the
power value is broken again. It's showing constantly
	power1:       85.74 W
in idle mode. setpci now says:

00fff83e (first try)

00fffffe (all other tries)


As I did it a few hours ago, I got 003930c9 and the reported values have
been between 26 W and 40 W (sounds reasonable to me) - before and after
entering setpci.



Thanks,
kind regards,
Andreas Hartmann
