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).
