OK so hpa's tree just had all of Linus' stuff pulled, not just rc8. It
turns out Eric Paris' inotify patches are required to fix 2.6.31-rc8
for me.. I tested just one patch and it fixed my bootup lag:

http://git.infradead.org/users/eparis/notify.git/commit/b962e7312ae87006aed6f68ceee94bdf8db08338

FWIW for that patch:

Tested-by: Luis R. Rodriguez <lrodriguez@...eros.com>

So -- you if you're like me and had issues with bootup lag on
wireless-testing, you can probably fix your wireless-testing by
pulling his patches:

git pull git://git.infradead.org/users/eparis/notify.git for-linus

I saw Linus had some other fixes but I'll wait for rc9 for that as my
box seems reasonably stable right now.
