If you're running 4.x, try: http://www.watson.org/~robert/freebsd/scan_ffs_freebsd4/ That's a port of the OpenBSD tool. There was a version adapted for UFS2 floating around somewhere also, but if you're running 4.x that's not an issue. It has a mode that spits out the disklabel -- make sure to run it on the disk slice so you get offsets relative to the slice.
