Frankly, I wouldn't want to fix this for K8 only - they're going away
anyway. And besides, this is a BIOS fix for a very small subset of very
early K8s. It probably shouldnt've been there in the first place but
at the time I did it I wanted to fix the whole world (I'm much more
reasonable now :-)).
IOW, I'd like to leave sleeping dogs lie if you don't mind.
