Then why start Yet Another(tm) mailing list for it as everyone has agreed
it isn't time for that yet.

The loader would be very different from PowerPC for any StrongARM
development platform I'm aware of -- DNARD and CATS.
Uh... you certainly seem to have forgotten about locore.s and pmap
modules. They are not "a breeze".

How about concentrating effort on just _one_ new platform (ok, two --
ia64 and powerpc)???

Yes and no. Depend ons what you're doing with the powerpc -- remember
the most interest for FreeBSD/PowerPC to date has been embedded products
and comm processors. They don't tend to be SMP boards. I really don't
see running on Mac G3/4 as the driving reason -- that machine is just the
reference and development platform.
