This is the last version posted:

http://marc.info/?l=linux-kernel&m=132775832509351&w=4

However, it only may help if you use the kernel-based hibernation i.e.
"echo disk > /sys/power/state" (that may be worth testing without the
patch too, but Fedora is using this AFAICS, so it probably has that
problem too).
