After I picked this to the 10.1 branch and tested I found the following
piglit regression:

	$ ~/src/piglit/bin/nv_conditional_render-blitframebuffer -auto 
	Probe color at (0,16)
	  Expected: 0.000000 1.000000 0.000000 0.000000
	  Observed: 1.000000 0.000000 0.000000 0.000000
	PIGLIT: {'result': 'fail' }

So I'm moving this patch off of the "applied" queue and onto a new
"rejected" queue as can be seen here:

	http://cworth.org/~cworth/mesa-stable-queue/

Feel free to follow up with any additional information that would be
useful, (such as an updated patch or a change to the relevant piglit
test).
