for what it's worth, although top show it is much better, when I look with
'powertop' the story still looks not to good (but definitely much better
than before Jakub's patch)
It still says 26.6 of 29.1 W (>90% ?)  is going to the wlan ? Seems like a
heck of a lot of power for wireless lan? makes no sense.  I'm not very
knowledgeable of powertop, perhaps I just do not understand the display.

by the way, this isn't streaming or anything, there is chrome running, with
a gmail window and some local terminals.  No real network traffic  at all.
