you will need to use a different first stage (magicboot) or none at
all (if OF will boot that way, some models refuse to autoboot
binaries without the CHRP bootinfos). the default ofboot script
installed with yaboot forces the output to screen to work around
stupid hacks in apple OF to prevent `archaic peecee text' from
appearing on the screen.

never modify the bootstrap partition, edit the magicboot= line in
/etc/yaboot.conf to point to an alternate script. you can make a copy
of the /usr/lib/yaboot/ofboot file, then find and change the line:
" screen" output
" ttya" output
later im going to fix this so it won't have this problem.
