On the other hand: Running OpenGL 2.0 Conformance Tests doesn't mean any game using OpenGL 2.0 will run without any visual flaws. These may still occur despite the fact that the drivers are OpenGL conform. Game developers and intel are required to go hand in hand, which hasn't always been the case in the past. E.g. game developers didn't test on intel platforms simply because those platforms wouldn't devliver the required 3D performance anyway.
