We've got several 64-bit architectures in Debian already, so I would
expect most packages to need at worst trivial changes, excepting the few
that need handwritten assembler and those that haven't been fixed for
alpha/ia64/s390x yet.

There's always the ia32-libs approach:

  Package: ia32-libs
  Version: 0.3
  Section: libs
  Priority: optional
  Architecture: ia64
  Installed-Size: 19660
  Maintainer: Bdale Garbee <bdale@gag.com>
  Description: IA-32 shared libraries for use on IA-64 systems
   This package delivers a set of pre-compiled ia32 (i386 family) shared
   libraries, so that ia32 Linux applications can be executed on ia64 systems.
