Anyone using powerpc (32-bit) will then need to add ppc64 as a foreign
architecture before they can install a 64-bit custom kernel.  This is
fine in principle, except that ppc64 is not an official Debian port and
its packages are not mirrored on the same servers.

I just tried something similar, which is to add x32 (also unofficial) as
an alternate architecture to my biarch x86 system.  APT now complains:

W: Failed to fetch http://http.debian.net/debian/dists/experimental/InRelease  Unable to find expected entry 'main/binary-x32/Packages' in Release file (Wrong sources.list entry or malformed file)

W: Failed to fetch http://http.debian.net/debian/dists/sid/Release  Unable to find expected entry 'main/binary-x32/Packages' in Release file (Wrong sources.list entry or malformed file)

W: Failed to fetch http://http.debian.net/debian/dists/testing/Release  Unable to find expected entry 'main/binary-x32/Packages' in Release file (Wrong sources.list entry or malformed file)

W: Failed to fetch http://http.debian.net/debian/dists/wheezy/Release  Unable to find expected entry 'main/binary-x32/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

So I think Michael's version, leaving big-endian kernels as powerpc by
default, is preferable for now.
