Why 6 bits for subunits?  What advantages, other than 14 bits of units, does
this offer over 12/8 split of the minor?  Remember, there are more devices
than disks, and device-specific flag bits should have somewhere to go.  4096
units seems quite adequate, and a need for more than that must be on a
Really Really Big System.  I believe that 12/8 gives us the maximum
