and to follow *that* up... turns out it needn't be as difficult as I
made it. I carry /var on a separate partition which means when I
remounted /var under the new 64bit system dpkg thought everything was
installed just fine, but of course it wasn't. so my subsequent dpkg
--set-selections call was a major problem. 

Anyway, word to the wise, when migrating like this, only take vital
parts of /var (like maybe /var/spool or /var/mail or whatever) and
definitely do *not* take the existing apt portions of /var. Instead
copy over the versions from the debootstrap install so that you get a
consistent archive.
