Branden, I am seeing this too. The important point here is that this is a
regression from 4.2.1, where the hardware is capable of DRI within an X
session of 1600x1200. Note that the resolution in question here is not the
resolution of the GLX graphic, but the resolution of the X display. That
is, the accelerated graphic I had working was at 640x480 and would appear
windowed or fullscreen via DGA.
Now glxinfo with LIBGL_DEBUG=verbose is reporting:
libGL error: XF86DRIQueryDirectRenderingCapable failed

I don't see anything that is obviously causing this to be triggered.
However, I am unsure about how this code fits in the wider implementation.
