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?
