So, one of the things that should be done eventually is to convert the
table entries in the device switches to pointers to similar table
entries in the drivers.

Once that's done, there's not too much to deal with.  Before then,
there's a bit of hair, but if you ever want to get a merged device
tree, your only chance to do it is while renumbering.

_I_ don't want to keep having to add devices to N (where N is large,
and growing 8-) device switches and MAKEDEV scripts, do you?
