Okay, I just tried to do a crossgrade in one of those disposable
chroots. The good news is that dpkg itself can be crossgraded smoothly
once the necessary amd64 libraries are installed, the bad news is that
apt gets thoroughly confused by this action:

This also means that my plan to "aptitude download base-files:amd64"
followed by "dpkg -i base-files*amd64.deb" does not work, so I'll revert
to the i386 dpkg in that chroot for now.
Cheers,
Sven
