The Intel gfx VGA option ROM on certain platforms requires the 155f50 BIOS function to be implemented (even if it does nothing), to work properly. This series of patch allow VGA passthrough on Xen to work on these platforms.
An example of these platform is the Dell Lattitude E6410 laptop, on which these patchs were tested.
