Perhaps you can keep your modified version of bind 8 running at a
different port (or even host), upgrade to bind 9 and forward all
requests for "special.umn.edu" to modified bind 8:

zone "special.umn.edu" {
	type forward; forward only;
	forwarders { <ip.of.bind8.server> port <alternate.port>; };
};
