2.6.33 may have some badness ahead too.  Somewhere in
the release cycle the INIT_WORK definition changed to
call the (new) __init_work function, which is GPL only.
This breaks the released OpenAFS kernel modules.

btw, as I recall, the 2.6.33 fc13 builds will otherwise
work OK on fc12 (if you also upgrade the linux-firmware rpm).
