<pre>From time to time, single glyphs get corrupted when using i965 sna. This
doesn't happen with i965 UXA. The corruptions go away e.g. when the window is
repainted.
Another problem is that the xterm window does not show the text anymore after
suspend/resume, until that window is minimized and restored. Do you want me to
file a separate bug for this?
Apart from these two problems, sna seems to work fine.
linux-3.10.5, libdrm, mesa, xserver, xf86-video-intel git. Using compiz-0.8.8.

Option "AccelMethod" "sna"
