After running for a while and a couple of suspends it seems like battery
life is worse with this kernel. When idle (and not touching the
touchpad) powertop reports a quite high wakeup rate.

Usage       Events/s    Category       Description
2,2 ms/s     133,0        Process        [irq/39-DLL060A:]

Top also report a fairly high cpu-usage (imo):
