The system knows nothing about MBR partitions. It just knows that
there are these "partition" things listed in the BSD disk label that
list sector ranges corresponding to partition a, b, c, etc. c is
traditionally the full MBR partition and d the full disk -- don't
touch those -- but you could easily point, say, h, at any range on the 
disk you want, including another full MBR partition.

Well, if you have your 0 drive, and you make the h partition point at
something, it will look like wd0h...
