This is a old discussion: http://lists.debian.org/debian-devel/2004/04/msg07233.html
With pure64 gentoo and experimental debian chroots I think that it is now possible to run some benchmarks (suggestions?). I agree that it is very important to be able to run 32 binaries, but a pure64 port is simpler and can be a good starting point for a multiarch if 64bits is the default or at least a good way to hunt bugs if 32bits becomes the default.
