Are you sure it's non existent? A G33 chipset should have it in
hardware I thought.

I'm not sure this is really the right way to handle this anyways.
If there's ever a working BIOS it will be blacklisted too. And
normally BIOS bugs don't come in one board alone, but in a range
of them and then adding more and more identifiers is quite painful.

Better would be to add some generic sanity checks that catches
the issues these BIOS revisions are having.
