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.
