   Note shark already had 'sd', 'uk', 'st'. If that is not correct,
   all scsi-related devices should be removed altogether.

possibly they shouldn't be there at all.  shark isn't really
expandable...  can 'st' attach at atapi?  shark does have a ide
controller onboard at least..
   
   The commit only completed the major list so that for each device
   group (scsi, wscons, isdn), all the devices would have assigned
   major. If the arch didn't have any scsi, wscons or isdn devices
   before, the list didn't change.

it just seems really dumb for a platform that will never support
something to have knowledge about it.  in the old days that would
not affect much, but in the new devsw world every device is know
about in every kernel so the above change wastes a few bytes ;-)
