Unfortunately, this proposed X server update has not resolved the problem on my system. I'm using a stock Ubuntu Lucid installation, compiz enabled, and with the proposed X server update.

Aside from disabling KMS, the only way in which I was able to stop this memory leak was to use a combination of the xorg- edgers packages and the mainline kernel 2.6.34-rc5. I am unsure which specific component eliminated the problem, but the problem disappeared only after installing kernel 2.6.34-rc5 [2] (which may or may not be coincidence, as an update in one of the xorg-edgers packages may have really solved the issue). I will now test the xorg- edgers packages against the official 2.6.32-21-generic kernel to try to isolate the problem. If you require any more information or a separate bug report filed, please let me know.
