If they don't haven't we just found a driver bug? Assuming you're testing on cards with the same capabilities (you would have to record what extensions should correspond to what results) I don't see why the output shouldn't be the same. As long as you keep the tests simple so that they don't try to do anything like dynamically adjusting detail based on load, and you do the tests with either the same aliasing/filtering or none, I would think results would have to be the same across cards in order for them to be considered OpenGL compliant.
