  Above, I canceled the second run very quickly, hit the up arrow>enter to
  re-run it very quickly, and it came back...
  
  This is just weird. As you can see from my first excerpt, my xorg.conf is empty.
  My refresh rate is obviously not 1500+Hz, it's the default for my DVI monitor, 60Hz.
  
  Reproducibility? Not sure how I reproduced it, just did it a bunch and
  the warning comes up occasionally.
  
  Good luck with this one,
  -Derek
  
  PS - Second bug(?) - Firefox seems to think 'framerate' is not a correct
  word... :)
