What I've done in one case is use LVM.  I had several logical volumes,
including ones for /, /home, /usr, /var, and /tmp.  When I upgraded the
hardware underlying the machine, I created separate logical volumes
called root64, usr64, and var64.  I installed the 64-bit system using
those logical volumes, copied over /etc from the old root to root64, and

This isn't automatic, but it was a lot easier than it might otherwise
have been.  It is, however, trivially automatable.  Multiarch might make
it even easier, I don't know.
