That functionality has been around awhile, probably at least around the time Vbox was introduced to FreeBSD ports. I used to use 64 bit VM's on a 32 bit FreeBSD host, but the only stipulation was only one 64 bit VM could be run at a time. I didn't have any stability issues. This was in the early 3.X series and I haven't tried recently. -- Adam Vande More
