They shouldn't have to, and the whole point of wedges is it shatters
the need for that, especially with the right tools. HOWEVER, I'm not
sure MBRs are the be all and end all of i386 labeling.

But of course, the tools needn't suck.

That isn't strictly needed, and in any case is fully automatable.
The point here is just to continue to maintain a way to slice up and
type BSD partitions within MBR slices -- NOT to force users to put DOS
partition info into the MBR to make accessing a DOS slice
possible. wedgeconfig completely obviates the need for that.
