If you want to try BFS on a 2.6.33 kernel, you can try this 'unofficial' port:
http://git.zen-kernel.org/?p=kernel/zen.git;a=shortlog;h=refs/heads/sched-bfs
I'm currently using it with no issues so far.

Your patch applies cleanly to 2.6.33-rc2, but compilation fails:

A stupid mismerge in __might_sleep meant that with the right config
options dmesg would have been swamped with false warnings. This also
was making BFS consume a lot of CPU under certain conditions in
combination with preempt RCU.
Thanks to Jayson R King for picking it up!
There are no other changes in this version compared to 312
full patch:

incremental:

I highly recommend BFS users upgrade.
