It very sad turnout. There was no rescheduling in earlier kernels (feisty, gutsy) and minimal achievable power consumption was 2W lower than now. I could go down to about 12W on idle on my laptop. With current hardy I couldn't get lower tha 14.3W, even with SATA link powermanagement on, with tickless, jiffy rounding and all other imrovements. This rescheduling issue appear to kill all gains from changes in kernel since feisty.
