I see that the "ATI Catalyst 9.8 Proprietary Linux x86 Display Driver" was released on 8/17/2009 at http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx?type=2.4.1&product=2.4.1.3.36&lang=English. Unfortunately the links for the Release Notes and Installer Instructions report "file not found" errors.
