It is possible to cross-build for amd64, but you'll need a seperate
partition to put the 64-bit environment on. Look at the mailing list
archives. This question has come up before.

But to keep things simple, I'd advise you to backup your files,
configuration files from /etc and possible /usr/ports/distfiles,
reinstall from an amd64 CD and then rebuild your kernel, world and ports
to your liking.
