Do you actually want the vga compatibility bits on pseries? There also is virtio-gpu-pci (same thing as virtio-vga but without vga compatibility), which should already be enabled on ppc64. The linux kvm driver certainly doesn't need vga compatibility. For slof support it might be useful though, the vga compatibility bits in virtio-vga are fully compatible to stdvga, so slof support should be as simple as adding a PCI ID ... cheers, Gerd
