It is weird that fuctory bios can still use them.
There's gotta be a hack in fuctory bios, I would guess, something like: if (the pci card is a vga && there is an option rom) callit();
i.e. I betcha that fuctory bioses will call an option rom on vga even if it violates the spec.
I wonder if we really want to do this, the S3 cards are antiques anyway.
