Wow, I didn't realize that there were two boot modes to OS X Snow Leopard! Indeed, if you boot up with the "6" and "4" keys held down the kernel boots 64-bit, but if you do nothing (or hold "3" and "2") you get 32-bit. Thanks for pointing this out. It's so different than what I've encountered on Linux/Windows, I would have never thought of it.
