So it's a 405 core + other board (I use the term loosely here) bits
attached on a bus, right?  I think more work might still need to be
done for seperating stuff that's specific to a certain 405 board from
the more generic 'board bits', but I don't think it'll be too hard,
or too dramatic.

So it's sort-of like throwing more PCI cards in a pmac?  They're always
on some sort of standard interface(s), yes?
