attached patch to vgabios-0.6a adds the pci data structure to
vga-cirrus.bin

This is needed to boot LinuxBIOSv3 with VGA enabled on Qemu

It seems the vgabios project has stalled, so I am sending this patch to
this list as well. Can you update the vga-cirrus.bin image to include
this pci data structure?
