This has already been accepted by the stable queue and pushed out as
part of the last 2.6.32 stable drop:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6-stable.git;a=commit;h=523273f08eb995890ab4c3012cb95fd07686de1c

Patches from the upstream -stable tree go through our SRU process
automatically. Stefan and others are probably in the process of
reviewing this and all the other patches right now. He will probably
have a better idea of when they will make it into a kernel release, but
it's on its way already :).
