The kernel 2.6.38-12.51 don't solves the problem for me. I see a little improvement in battery life (from 4h to 4h30'), but powertop doesn't notice any reduction in power usage in idle. Moreover, the optimal battery life of my netbook should be about 6h. ( aspm parameter at boot does nothing). I'm with a Zareason Terra HD (Intel Atom N450 and Wifi Link 5100). I'm going to open a new bug a suggested, but with the oncoming release of Oneiric in a few days.
