heh.  Well, chrp and pmac really should use yaboot or something similar.
I'd go as far as to say on a machine which reasonably could be used for
desktop (and thus the choice of multiple kernels) you want something to
find where they are and let you pick one.

In other words, do all of the stuff the in-kernel 'bootloader' does.
I don't think this is a problem in a stable line.  This stuff shouldn't
change in a way that's not backwards compat.   We've diddled this
a bit along the way in 2.2 and 2.4 I'm sure, but we shouldn't.

heh.  Well, I do think we should outline what we're going to attempt to
do a bit and then throw out some code that does it.  There's other
people who for some reason or another want to have a bootloader external
to the tree, and I think that's a good idea.  I'd go as far as yanking
our in-kernel crap out and making it it's own package once we got things
settled down perhaps...  But that's just my opinion. :)
