Hi Hannu,
I tried getting this working on OpenBSD/amd64 and ran into a problem as well..
Here is the string I boot the installer with:
qemu-system-ppc -M mac99,via=pmu-adb,graphics=off \
-cpu g4 -nographic -m 2048M -vga none \
-hda macppc.img \
-nic none \
-cdrom install66.iso -boot d
This way will panic the kernel on boot, so one needs to quickly get into the
kernel config by typign -c at the boot: and then disable the ohci with the
command "disable ohci" and then "quit".
This will take it to the installer but there is an openpic message that keeps
repeating saying something like:
qemu-system-ppc: openpic_iack: bad raised IRQ 47 ctpr 7 ivpr 0x4047002f
qemu-system-ppc: openpic_iack: bad raised IRQ 47 ctpr 7 ivpr 0x4047002f
It emanates from qemu so I installed a patch to squelch it becuase I'M unsure
how to do this inside qemu.

So then I was able to install OpenBSD/macppc on the disk wd0. However it
doesn't boot (like you said)... I get the message:
Welcome to OpenBIOS v1.1 built on Oct 28 2019 17:09
Trying hd:,\\:tbxi...
>> Not a bootable ELF image
Anyhow after working with it on -current and then trying 6.6 I gave up on it
tonight. Also... I get panics when I select any nic device. That's where it
is I guess. Hoping someone picks up on my work, or leaves it be.
Good night!
