This patch enables the VGAHOOKS config option if the BIOS is configured for Xen. In the Xen VGA passthrough case, the option ROM can be extracted from the physical device by hvmloader and pre-deployed for seabios. This patch also allows setting up VGA hooks in case the VGA option ROM is already deployed by hvmloader.
