I'm inclined to agree. Not that I think 380fps sounds very impressive (I 
get 850+ fps with _software_ rendering, for chissake), but because 85 fps 
is a joke, and clearly without this setup there's not even any point to 
try to do any other optimizations.

And if we're looking at the patches being in Fedora anyway, there really 
is no reason not to merge them. Even if it's out of the merge window.
