Oh! Thank you. Yes, that's an interesting case.
In addition to amd64/i386, it occurs to me that sparc64/sparc32 is
another case; IIRC it's possible to take sparc64 hardware and build a
(special? not sure) kernel that runs sparc32 userland. I've never
tried it; I don't know whether sparc32 and sparc64 are as freely
mixable at runtime as amd64 and i386 are under amd64 kernels.
