Sounds like an one off thing, so in your case forcing the installation
should work:

	dpkg --force-architecture linux-image-*.deb

The problem with that approach is that it doesn't work with APT, but I
doubt that there are any private APT repositories with this environment.

The issue with one kernel and 2 userspaces will also arise in sparc,
when the sparc64 userland gets going. So it will need to be dealt with
at some point, so I create a 3 lines additional patch for it.
