I set up a fake root directory, extract a minimal i386 FreeBSD system into it. The attached script is used to start a 32bit chroot-ed environment, either to run a command or start a shell. I have successfully built a large number of 32-bit ports on a amd64 bit server this way. Let me know if you have more questions.
