On my machine, it's greyed out as well, which suggests my CPU doesn't 
support the extensions.  So why would the check box be checked?

Are the extensions necessary to use VirtualBox on FreeBSD at the moment?

Is there anything else I can test or any more information I can give to 
figure out why my kernel is panicking with VirtualBox?
