hfsplus is the package you need. It allows you to copy files to a
Linux system by binhexing or macbinarizing the files as it copies. So,
if you have enough room, don't bother tar'ing, just copy everything
you need off (assuming it mounts). When you copy back with the same
tool the process will be reversed.
