FWIW, I applied the whole bunch of
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c4efd6b569b2646e1346a08a4c40286f8bcb5f11
to the stable 2.6.35.1 and it fixes the wake ups mostly. I still have
~20 wakeup/s from load balance tick but it's way down from ~200 on my
system.

Specifically the "Revert nohz_ratelimit() for now" commit makes it
better, I had a kernel with only that one applied and it helped as well.
