Recent versions of VirtualBox claim to be able to run a 64-bit VM on a 32-bit host if the host CPU is 64-bit and has hardware virtualization support: http://forums.virtualbox.org/viewtopic.php?p=33940 (search for "64-bit guest") So far I've only seen guest kernel panics when booting the kernel on an E8400 i386 FreeBSD host.
