Dagnabbit.. it's done it again.. went from 100-200 wakeups/sec
back up to 20000+ wakeups/sec. This time *with* the powertop patches in place.
Somethings broken in there, but I don't know what.
Or how to make it happen on demand.. it's fine after rebooting again.

???

At least now I know to look when I hear the fan turning on
when the system is otherwise supposed to be idle..

2.6.23 did not have this problem.
