I don't know which (if any) other cards apple offered for these
machines. I suppose it wouldn't hurt, but OTOH, if this card is all
that was offered, it's probably not that big a deal as it would be
unlikely that another card with a mac vbios would show up in one.
Cards with an x86 vbios won't hit this path.
