IMHO, that's the simplest solution and the only one really compliant with our packaging guidelines (support all architecture variants by default, provide optimized versions as optionals). Of course the root of the problem is ATLAS's lack of support for runtime CPU feature detection (which is the recommended solution for Fedora packaging), but I don't expect that to get fixed any time soon. (The ATLAS developers expect everybody to compile a tuned ATLAS for their own machine and show only very limited interest in binary packaging.)
