A kernel-image-2.6.6-5-amd64-generic_2.6.6-5_i386.deb is being
prepared and should be available in a few weeks when it has passwd
queue/NEW handling.
Once you have rebootet into that kernel you can (c)debootstrap a
pure64 chroot and start using 64bit programs from within the
chroot. This would be the normal way for anyone wanting to take a
peek. Everyone that commits to pure64 has to install anew.

That is only possible with multiarch and that is a long way off.

Not possible and not intended for pure64. This will never be supported
by pure64 and would be a major hacking around. If you want to do this
better create a new partition, copy etc and the debconf db over and
then run cdebootstrap and install all previously installed packages
again.
