If you want more partitions per disk, help get wedges working. One of the 
ideas with wedges is that we have a wedge major, then we have minors off 
of it. We do not use the unit/partition split with wedges, thus there is 
no limit on the number per disk.

While I really don't see a need to raise the size of dev_t, if we're 
bumping libc, maybe we should.

Take care,
