I've just started messing around with powertop 2.1, and I notice something
that strikes me as decidedly ODD...

On my eeepc 901, powertop reports that network interface p33p1 consumes
in the range of 5.6 to 7.7 watts, depending on factors that aren't
obvious to me.

it doesn't seem to matter if there's a cable (and resulting working
network connection) or not.

The next highest consumption devices reported are the USB network dongle
at 1.19 watts and wireless network at 1.12 watts.

5.6 watts seems AWFULLY high...

Aanybody got any insight into this? thanks!
