If we want to limit our offer to two binary architectures I'm for
x86_64 maybe with SSE3 enabled (kicks out oldest Athlon XPs) and keep
i686 with least features needed for full compatibility. I could even
live with i586 for fallback. Though I'd prefer to
fully drop 32bit and rather leave it up to the community if they want
to keep it alive any longer.
