I do not think that multiarch build (ie 32 and 64 at the same time) are fully supported yet on Ubuntu or Debian. It is coming, but just like a number of other things, not exactly overnight. It is a release goal. In the meantime, you can always use virtualization. I have a Debian 32-bit system and an Ubuntu 32-bit system in KVM virtualization on my Ubuntu 64-bit server. That works well. Kvm, or Xen, or Virtualbox, or Vmware, ... all offer fairly decent virtualization. Debian/Ubuntu specific questions are even more welcome on r-sig-debian.
