I am going to go out on a limb and guess we're going to see a crapload
of reports of "performance regression" due to reduced glxgears frame
rates.

Mayhaps this could be headed off by changing glxgears output a bit?
Something like:

 $ glxgears
 Failed to initialize TTM buffer manager.  Falling back to classic.
 300 frames in 5.0 seconds = 100.0% synchronized
 299 frames in 5.0 seconds = 99.93% synchronized
 300 frames in 5.0 seconds = 100.0% synchronized
