I don't think so - PC's have a partition table. Us FreeBSDers call these
partitions 'slices', and subdivide these into FreeBSD partitions. Each
slice (pc partition) has a disklabel which denotes where the FreeBSD partitions
live on the slice.
I see what you were saying now above now. I agree that the superblock for
a UFS file system won't tell anything about other UFS partitions, but
a block by block search of the whole slice will identify potential
superblocks that will.
