I'll test the mainlines shortly. Upgraded to the current (-5?) kernel made it a bit better, consumes 22W/13W depending on if the i915 is stuck at 1300MHz or not. Also, the problems start after suspend/resume, things are fine right after booting it up.
** Description changed: I recently upgraded to raring, and now it consumes >24W instead of 7-8W - on idle. This is a hybrid laptop, but only the discrete GPU is in use. + on idle. This is a hybrid laptop, but only the integrated GPU is in use. Powertop shows 'Timer' causing a lot of interrupts, CPU frequency is at it's lowest though.
