What you see on you Athlon system is the situation and ok. Fedora Core 1
is still i386 based, only glibc may vary like on your's which is i686,
and the kernel is CPU dependent compiled. You see last by using "uname
-a".

What do you expect by having a i686 based architecture compile? You
might only gain just a few percentages of speed, if though.

As far as I see at the rpm macros, Fedora is using prelinking, which
normally brings you most performance gains using different applications.
