Well, the fact that BIOSes aren't open source means that anyway. As far
as we the users are concerned, the BIOS is black box code which runs
with the ultimate in administrative privileges. It could be doing
_anything_ back there. SMM is a fairly standardized example of this,
sure, but there's no way we can really be sure our BIOS isn't doing a
zillion other 'bad things'. The point where you tip over into excessive
paranoia is a bit hard to discern when you start going down this road,
