Confirmed the following two kernel patches together fix the problem perfectly for Mir: http://lists.freedesktop.org/archives/dri-devel/2013-August/043406.html http://lists.freedesktop.org/archives/dri-devel/2013-August/043407.html
Now Mir under nouveau is always 60Hz with no tearing.
Unfortunately the patches make legacy X/Compiz much worse... only about 30Hz.
