The best they could do at the time (Score 4, Insightful)

Doesn't it seem logical that the tarball they released was the best they could do at the time? I bet if you look through the CVS repository they just released, you'll see some Intel specific stuff, maybe even just a check-in comment. That would have blown their big secret. Which, incidentally, is amazing they managed to keep that secret for 5 YEARS!
