I guess running an Enterprise distribution doesn't help at all :-) But what values for both options may help the most when you want this enabled and get the best result ? It would be nice as a user/system engineer if we could query the value of kernel module options on a running system in /sys. I don't think that is currently possible, is it ?

PowerTOP reports wakeups, but is it possible to have a function called badsleep() that wakes up when some part of the system makes a noise? So if PowerTOP would report "Wakeups-from-idle per second : 30.8", the average sleep time of badsleep() would be about 30ms. badsleep() would allow applications to have regular opportunities for activity without causing extra wakeups-from-idle.

May be there are bugs filed already. It would be great if you could do some quick analysis on this for us the mere mortals who can't get all of this amazing work in our systems (just yet).
