When Intel proposed the CPUID in the Pentium III, everyone panicked. I felt confident that, if there were nefarious things happening at that level, people would have figured it out. After many months of hand-wringing in the tech spaces of the time (/., et. al.), people started waking up to the fact that Intel had, in fact, already buried the CPUID in the Pentium II all along, and "we" had already been "had." Moral of the story: do not ever trust that "it would have been news already," for anything.
