2.6.29 isn't good enough, you need the patch at
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d08e2ce0ebb38f2b66d875a09ebab3ed548354ee
which only hit Linus' tree 3 days ago.
I'm not sure whether it is appropriate for that patch to go to -stable. There
are other patches that affect the relevant code but that one looks like it is
a fix for a real bug that should apply cleanly to 2.6.29.
I guess if you are able to confirm if it fixes 2.6.29 for you that would be a
good indication it is appropriate for -stable.
