And that is a problem?

They aren't exactly cross build. Just with -m64. This is supported
upstream in both kernel and gcc and it better not have abi
differences. It is also used in libc6, gcc, fakeroot, zlib1g and a
bunch of other packages during build.
The same method (but much less elegantly) was used in sarge and nobody
has reported problems there, have they? So I guess we can rule that out.

I asked this before and haven't yet recieved an answere:
What does w-b do when the amd64 build uploads amd64+i386 64bit kernel
debs but not 32bit. Afaik the package should be detected as incomplete
and set to "needs-build" for i386. i386 then builds the 32bit kernels
only and uploads them.
Unless someone is willing to test this technical aspect repackaging
seems out of question.

Which means, at a minimum, changes to debian-cd and D-I to include the
amd64 packages on i386 and the linux64 boot option and a wrapper
package for apt/aptitude/dpkg to make the amd64 debs appear and
installable.
If the patch for 64bit kernel won't get accepted I can upload the
wrapper package.
