This looks like an artifact of however you installed the 12.2 drivers that were never in precise, most likely it did not rebuild the kernel module against the kernel update. Please uninstall the same way you installed them and then switch to the precise drivers drivers. In the future, pass --buildpkg Ubuntu/precise to the installer from amd.com to build .deb's and install those instead of installing directly to not have this happen.
