I'd much prefer if yum depsolver could handle this instead of making
everyone use kludges like %{_isa} in the spec files. It's perfectly fine
if rpm accepts the "wrong" arch. Yum, however, should be tailored for
the way we are doing multilib in Fedora and just do the right thing.

I would be hard pressed to find any real life case where picking the 32
bit package instead of the 64 bit one would give any advantage, provided
that both are coming from Fedora repos.

Seth, have you considered making arch distance give more than the 5
points it currently has in the yum depsolver scoring logic?
