Markku, I've tried the current livna rpms for fglrx in their testing section. However the problem is that while glxgears works under fglrx I find that programs like pymol (http://pymol.sourceforge.net) segfault when rendering. FYI, this is on x86_64 of course. I know my x86_64 build of pymol is fine because the same type of build has no problems with the fglrx drivers on a AGP based Radeon on another x86_64 machine with FC4. Jack
