Why is the athlon optimised compiled kernel available in Fedora? Also if I try to rebuild from SRPM, it tells me that athlon architecture is not included.
There is no Athlon specific kernel in FC2 because one is not needed. The 2.6 kernel is clever enough to handle any Athlon specific optimisations on the fly rather than having to have them compiled in. Just use the i686 kernel instead.
