We keep an opteron around with LFS and Gentoo on it (dual boot) to build monolithic kernels
for our postgres Opteron servers. I've built one in the Biarch chroot
but had problems with modules and the biarch vs debian sarge
module-init-tools versions. As long as I'm going monolithic, i just use
kernel.org sources and manual build style on the dev opteron.

We did not use the raw postgres /data directory, but copied a pg_dump
over of the database and it worked fine. Full test sets on debian 32
bit postgres vs debian pure64 postgres in a chroot and the dev
environment's results on the same test set will be available by the end
of May.
