State-Changed-Why:
On non-512 byte media the disklabel has to remain at the same byte
offset from the start of the disk. Otherwise the space in the
bootcode isn't in thecorrect place for teh label.
disklabel now always does an 8k rmw on the start of the disk (or
mbr partition) regardless of the physical sectot size.
