It could well be that a bug in FreeBSD is triggering the bug in VirtualBox, 
but we're unlikely to make much headway debugging the FreeBSD bug (if any) 
until the bug in VirtualBox is diagnosed/fixed.  I'm not sure what the normal 
debugging procedure for vbox panics on Mac OS X is, but I'd suggest making a 
backup copy of the bad VM so that you can trigger it on demand later.

This, on the other hand, could be our bug; there's a new USB stack in 8.0.  I 
suggest creating a new thread for that issue with a usb-related subject line 
to make sure the right folk see it.
