Sure. I think at worst we should aim to end up with as many flavour as
we have today, in reality I expect we should be able to end up with
fewer (even if only -= 1).

BTW, someone (I forget who) at Debconf in Cambridge last year floated
the idea of putting a stage 2 loader in flash to pull the real kernel
from some larger storage. I don't know if that is realistic here, and in
any case I don't intend to work on it myself.
