Ok, so you tried booting debian, can you tell me exactly what media did you
use exactly. (complete URL to it ?)

Ahah, this is indeed a yaboot-installer bug, i think you should file a bug
report against yaboot-installer explaining all this.

You need a prep partition (type 0x81) and ybin (the yaboot copying of binary)
or whatever needs to recognize your machine as a ibm/chrp box, and act
accordyingly.
You could try installing using prep-installer, which should work on your
system, but you need to create a prep partition, and i guess partman-prep
doesn't recognize your box as needing a prep aprtition.
Colin, would you comment on this, i believe we need some other kind of sanity
checks, one that makes sure that there is a prep partition on such machine,
even though they use yaboot. I wonder why partman-prep did not do the right
thing though.

hope this helped a bit, but i fear it is a bug in the installer, maybe fixed
in a later version than the one you used, not sure though.
