--- Comment #11 from Chris Wilson <chris at chris-wilson.co.uk> ---
Hmm, I wonder if we can start from 12.10 and install components piecemeal until
it fails. I doubt that is very practical.

What may be easier is to start with 13.04 and downgrade mesa to 9.0.0 by
compiling it by hand, and similarly for the kernel. You can also flip the
xf86-video-intel over to UXA (but given how it persists between
UXA/SNA/blt/glamor on tip, I guess it is not the ddx).

I would start with compiling mesa.
I guess something like apt-get build-dep libgl1-mesa-dri and git clone
git://anongit.freedesktop.org/mesa/mesa and a bare ./configure --prefix=/usr
should be enough to achieve the downgrade. (If you want to be safer, just build
a chroot for 13.04.)
