With 2.6.30 rc2 and xserver-xorg-video-intel 2:2.6.99.1+git20090416.b9716b83-0ubuntu0tormod from xorg-edgers ppa I get 1400 fps in glxgears in exa mode with Kwin compositing disabled, and ~700 with compositing enabled. This also helps me work around the annoying suspend-to-ram crashes I get with UXA and still have good performance.
