Done that, it mostly works. You can also build your own 64-bit kernel using a 32-bit userland. If I remember correctly, the big thing that breaks is iptables (the 32-bit and 64-bit interfaces are different, or at least were)I never did this myself, but I saw someone at DebConf6 who installed an amd64 kernel on a sarge i386 system using the --force-architecture option.
