I'm not sure I understand your bug report, or exactly which patch you're referring to...
My guess is that you experience performance issues with EXA and when we (briefly) switched back to XAA for <965 you saw a performance increase? If this is the case, then I think I may have a better fix I can apply... let me know.
Also, please attach your /var/log/Xorg.0.log and /etc/X11/xorg files.
