Yesterday I install fresh kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc8/ and upgrade Xorg packages from https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
"Device" section in xorg.conf: Section "Device" Identifier "Configured Video Device" Option "AccelMethod" "UXA" EndSection
Performance is good, OpenGL applications working well with compiz.
