Bug#613241: xserver-xorg-video-intel: rendering corruptions if "tiling" is enabled on

thanks for the pointers. If you have some time to spend, it might be
interesting to give a try to a newer kernel, or maybe even to a newer
version of the intel driver. We're planning on backporting it to
squeeze from time to time, but it would be nice to know in advance
whether that's fixed upstream already, or whether we should have this
report forwarded upstream.
