pci_fixup_video turns into generic code because there are many platforms need this fixup for embedded VGA as well as x86. The Video BIOS integrates into System BIOS on a machine has embedded VGA although embedded VGA generally don't have PCI ROM. As a result, embedded VGA need the way that the sysfs rom points to the Video BIOS of System RAM (0xC0000). PCI-to-PCI Bridge Architecture specification describes the condition whether or not PCI ROM forwards VGA compatible memory address. fixup_video suits this specification. Although the Video ROM generally implements in x86 code regardless of platform, some application such as X Window System can run this code by dosemu86. Therefore, pci_fixup_video should turn into generic code.
