Can't stress powertop enough. I have a N455 Atom netbook, with 11.01, just now installed it (I knew about it but always forget to install it after reformatting), and using powertop's suggestions, I brought idling down from an average 8.5 watts to 7.9 watts, giving me almost another 30 minutes of battery life.
