Thanks! I don't think it would be appropriate to update the Bochs standard with a feature that they don't use. And on reflection, perhaps the compatibility-oriented VGA device is big enough already. My plan is to write a Mac OS 9/X "ndrv" targeting virtio-gpu. All going this well, this might become the default mac99 GPU until ati-vga is ready. But virtio-gpu is not compiled into qemu-system-ppc by default. What is the difference between CONFIG_VIRTIO_(GPU|PCI|VGA)? And is configs/devices/ppc-softmmu/default.mak the correct place to declare them?
