Thank you both. (i think we always learn more watching a spirited discussion than if everyone just tediously agrees)
i lost track of LinuxBIOS and am glad to see that work on it continues. of course, i was thinking more of an unlikely... -patch- to remove, or jumper around, UEFI, instead of the full nuclear option; but that might be the only way in the final analysis. as long as hardware makers are willing manufacture to suit a narrow, (yet fat), market.
