Currently we know that mac99 is a hybrid of several machine types, but
it just so happens that the OSs contain a large enough range of drivers
for the image to work, as they appear to do here.

If it helps, I've just noticed that the OS 9 patchset also fixes NetBSD
PPC boot (looking at the CUDA driver I suspect it is likely the I2C
parts) so I don't think FreeBSD will be too far off.
>From what I've seen of reports from OpenBSD (e.g.
http://virtuallyfun.superglobalmegacorp.com/2015/07/19/gsoc-bringing-macos-9-to-qemu/),
my first guess would be that a good starting point would be to check to
PCI host bridge properties generated in OpenBIOS.

I've just pushed the rebased version to
https://github.com/mcayland/qemu/tree/ppc-os9-upstream for people
interested to test further.
