Particularly why not to automatically install the whole x86_64 distro where appropriate? The DVD media should contain both arches as in the real world found out the users are not aware if they have 64bit-capable hardware. x86_64 provides CPU instruction set + ABI improvements which usually overcome its only performance disadvantage of larger addresses, some benchmarks at: http://www.amd64.org/fileadmin/user_upload/pub/64bit_Linux-Myths_and_Facts.pdf Guessing some software (codecs?) may fallback on 64-bit to unoptimized C code instead of some assembly one but Fedora would at least show the usefulness of the updates of such software for the x86_64 arch.
