The mesa you have doesn't support non-kms anymore. So if you haven't
downgraded that, too, dead-slow opengl is expected ;)

I've taken a quick look. The gpu jumped to a location where there's no
batchbuffer. Likely some memory corruption, but can't say for sure.

You don't have to. But it would be great if you could upgrade to latest
libdrm and xf86-video-intel from git master, there have been quite a few
bug-fixes since the last release. Get them from
http://cgit.freedesktop.org/mesa/drm
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/
Compile&install libdrm first (otherwise you get a non-working system).

Thanks for testing, Daniel
