Of course, one could argue that since all of those were obsolete by the

isVGA == 0 pretty much means the more obvious thing.

MDA/HGC stuck around for quite a while for debugging, since it was
non-conflicting with VGA, but even if it is, the reason people put it in
their system is to have something that the OS doesn't readily see.

so the kexec tools need to scan the pci devices list, and find out how
to set real_mode.isVGA and orig_video_mode, also need to parse the
comand line about vga console.
