Hmm, I guess I got confused because the linux 2.6.26 kernel detects it
as type 66 (Blue&White G3).  ANd of course I read somewhere that
openfirmware 3 was only ever used on newworld Macs, and that seems to be
what openbios implements.

I can't get quik to work, but yaboot works.  Well after convincing it
that it was a newworld machine.

According to the powermac setup in the linux kernel, only newworld
machines have the entry for 'interrupt-controller' so you must mean qemu
emulates oldworld, which is what you said at the top.

Yeah I noticed.  So far mac99 didn't seem functional to me.

So it seemed.

Hmm, OK.  I will try that.

So for some reason I have it working with yaboot (which is supposedly
only for newworld machines) along with openbios.  Hmm.
