Apparently the Steam link is referring to this post:

As that one is the only one updated today that says anything even remotely similar to what is said in the Steam post.
So, according to Steam: new drivers today or tomorrow.
Also, there are reports that the new AMD OpenGL driver for RAGE breaks other common OpenGL applications:
