one thing we found in getting penguinppc booting quik is there is
something bogus going on in OF, and putting some random crap in
boot-file seems to work around it.

without boot-file set quik comes up like a terminal where you have
just cated a binary file.  and it refuses to boot.  it used to be
boot-file was set to:

ide0/disk@0:7/vmlinux root=/dev/hda7

which is totally bogus for two reasons:

it does not start with a space. 

/vmlinux does not exist.  

now its set to ' video=offb' however in both cases the kernel reports
its command line as something like this:

root=/dev/hda7 ro aÄäh

with some binary crap at the end. boot-file is supposed to be the
command line arguments passed to quik, but quik is apparently getting
binary crap instead.  but it pushes enough crap out of the way to keep
from f00king up quik. 

this is on a beige g3, with apple's OF nvram patches.  using debian's

just some observations probably not much help...
