They are just wrong.  The wrong names were introduced in rev.1.10
(1995/12/08) of dgb.c and never fixed.  Wrong ownerships and
permissions were introduced then too.  I fixed many similar bugs,
but only for devices created by `sh MAKEDEV all'.

The above names don't sort very well.

They must be consistent with MAKEDEV.  The last 2 or 3 characters of the
names for the non-control must uniquely indentify the device for use in
ps, etc.
