x86_64 support

[Karl Lattimer <karl nncc info>]

Hi there,
  It seems there is no x86_64 support for AMD opteron/athlon 64bit? Is
this intentional or is it an oversight? I am running an old Fedora Core
2 server with an ath64 in it. I don't get any updates anymore, luckily
it is behind a firewall and because of the nature of the server I can't
upgrade it entirely very easily, I would however like to make sure that
I've got all available security updates.

Kind regards,
  Karl,
