There's btrfs-select-super, which is in the git repo for btrfs tools, in the next or tmp branches. That should allow you to select an alternative superblock to use, which (I think) will help you. If it is just your superblock that's damaged, that should help. You can check whether it's likely to be of use by running "btrfsck -s 1" on your filesystem. If it passes OK, then btrfs-select-super should be useful.
