I'm sure a BIOS update would do it, but if someone is buying a new motherboard who aren't any wiser, they're going to but the one that states it's ready, not one that doesn't (and yet has a bios update). That said, these are newer revisions of existing boards, so even if the old board does support it, you would expect the new ones to be better.
