the way i handle this is to use raidframe. i boot multiple systems
from OFW-visible disk but root on the other disks, eg booting from
wd0, root on raid1 from wd1/wd2. with 'raidctl -A root' you can
force a raid disk to be considered as root.
this won't need a special kernel, but it does require special setup.
you *can* also do it with a single-sided mirror, if you're not trying
to use raid1.

i don't think this will work, because ofwboot doesn't have drivers
for the wd0 i bet.. the kernel and ofwboot need to exist on the
