The lesson learned is that if you upload a 0.0 or an 1.0 as a vertex component what you get on an nvidia GPU is not always interpreted as a 0.0 or a 1.0, and thus a == test to either may fail when it shouldn't have? but not like, all the time, just sometimes??? There's a story here, but alas I don't think we'll get to hear it.
