Well, the performance counters are easily locked down. Contrary to how the article is worded, the driver controls access to those - it's not merely a matter of being able to compile and run an OpenGL program (and I'm also puzzled at the singling-out of OpenGL, here).

As for the 3rd attack, that's rather more disturbing. It's a bit more like the hyperthreading-based CPU exploits. You could protect against it by imposing more stringent limits on how the GPU is shared, but user experience could suffer.
