From what I can tell, and please correct me if this is not the case, I believe there are no changes to the lvm structure, so you could take a redhat 5 system and boot a redhat 6 recovery disk or live CD and use lvconvert --merge to revert to the origin to a snapshot. You probably need to reboot anyway in order to use 'lvconvert --merge', since you can't revert an active volume.
