I'm working on such a Direct Host Graphics custom "videocard". I'm
reusing the common vga code, while adding an mmio and framebuffer range
for the direct stuff. Also it has a custom pci vendor/device id. It is
working quiet nicely, however, plenty of guest os drivers are needed
(preferably for different Windows versions - for Linux I have mine).
