I've taken a moment to ask one of my pretty chart scripts to dump a list of all SRPMs that are nvr-identical in both v5 and v7 repos-so-far. I put the list here: http://djdelorie.fedorapeople.org/arm-v5-v7-same.txt The list doesn't include a few key SRPMs we know we'll need, though, like kernel, gcc, glibc, and PackageKit.
