After reading the comments I feel this is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/583891
I also recover by running /usr/bin/metacity --replace from an icon I have placed in the panel.
I have tried using latest kernel 2.6.35-17-generic from sudo add-apt-repository ppa:kernel-ppa/pre-proposed
but still get this problem
[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!
