I'm happy to report my first amd64 installation (Aug 15th monolithic onto an ASUS A8V Deluxe) went smoothly except for the problem with none of the packages passing the debsig-verify function so nothing would install.
After doing:
cd /usr/bin
mv debsig-verify debsig-verify.real
ln -s /bin/true debsig-verify
everything else proceeded smoothly.
Thanks to everyone who made the port happen.
