I also see waiting for root device on Mac OS 10.2. Mac OS 10.0 has a kernel panic. Excellent job. This patch is a step in the right direction.

Too bad this patch comes a day after QEMU 1.3.1 is released. Hopefully it will be included in the next release.

Does anyone know what is wrong with the Mac99 target? I think it has the potential of being a better target than an emulated Beige G3.

Nice work Amadeusz! Is this using unpatched OpenBIOS SVN trunk? How far 
does it get with -M mac99?

Andreas mentioned in an earlier post when trying to boot FreeBSD that 
the "interrupt-parent" property wasn't being populated for the via-cuda 
and ata-1/2/3 devices which may be a starting point?

I played a bit with openbios, however it seems to panic not recognizing
the model, I tried few values but to no avail. (I could probably copy
from oldworld, but then what is purpose of newworld?)

Talking of interrupts I had to enable APPL,interrupts on newworld to make
it boot so there may be something wrong with them.

For now I think there are better chances of making default (g3beige)
target to boot than mac99.
