-vga std works fine, -vga qxl, I haven't tried on ppc yet at all...

The thing with cirrus is that it's the default in many cases (libvirt,
openstack, you name it it's there...) so it would be good to get it
working.

I already have fixes for the X driver (mostly some bugs where it stores
PCI physical addresses in 32-bit quantities) and I'm fixing cirrusfb now
but the later hits the color expansion path, so it looks like we'll have
to fix kvm/ppc to do the right thing there too :-)

Cheers,
Ben.
