As has been pointed out, you could use the "negate" plug-in, but I  
think doing this is fundamentally wrong.  The DNS is one of those  
services that has been beautifully designed to handle server/node  
failure gracefully.  The proper way of hosting highly available name  
service is to have all the nameservers up and running.  If you have  
just the two, then make it critical when one fails; if you have more,  
you can set up a Nagios cluster monitor and just issue a warning if  
one goes down.  Hacking scripts & anti-parallel monitors together to  
make sure you have a nameserver up isn't very elegant, manageable, or  
scalable.
