There's a patch-train available at https://reviews.freebsd.org/D37560, but I don't know if you'll be able to easily apply it (there's 22 reviews). Alternatively, you can try the boot-devs branch at https://github.com/bsdimp/freebsd.git which is the same thing. > > Alternatively, if someone has the recipe for FreeBSD/powerpc on QEMU that > > includes OpenFirmware for disks and networking, I'll do the testing and > > legwork to get my netboot setup locally. > > I'll play with that as well.

I've managed to get mac99 emulation on qemu-system-powerpc working well enough to do the test boot, at least for disks. Still haven't found the secret decoder ring for netbooting with openfirmware, though. There's a network stack in the current Open BIOS used by qemu, though, so there may be hope.
