A word of warning for anyone else who wishes to try this: while running an amd64 kernel on an i386 architecture installation is supported by Debian, it may not be supported by whatever third-party applications you're running. Some applications use the kernel's reported architecture to decide whether they should attempt to run a 64-bit or a 32-bit version of their programs -- and if the kernel mismatches the Debian architecture, they may try the wrong one.
