Maybe I am misinterpreting the problem.  When I was managing a mixed
AD-BIND DNS scenario, ALL of the computers used the BIND servers for
their DNS resolution; none used the AD servers.  But I had all of the
AD zones slaved on my BIND servers, so there was no need for any machine
to use the AD servers for DNS resolution.  The AD servers had only
the AD zones, so if any machine queried the AD server for a non-AD zone,
the request would have been forwarded to the BIND servers anyway.
