I wrote the MI kern/subr_disk_mbr.c with a view to it being a basis
for a common routine, however nothing has really been changed to use it.

msdosfs will work, but you have to jump through hoops to get a disklabel
into the kernel.
With a few minor modifications kern/subr_disk_mbr.c would do the job
for more of the architectures.

One problem is that you can't tell the size of the netbsd disklabel
(8 or 16 partitions) because the 'number of partitions' field is set
to a useless value.
