Yes, this seems to work.  We fake stub trick, that is:

zone "de" {
        type stub;
        file "/etc/bind/c/db.de";
        masters { 127.0.0.2; };
};

And db.de (which should be mode 0444) contains:

$TTL 7200
@ 86400   IN  SOA     f.nic.de. its.denic.de. 1 7200 7200 3600000 7200
        IN NS auth-ams.dnssec.denic.de.
        IN NS auth-fra.dnssec.denic.de.

auth-ams.dnssec.denic.de. IN A 87.233.175.25
auth-fra.dnssec.denic.de. IN A 81.91.161.228
