Classless in-addr.arpa zone in BIND 9.1.1rc4 ?

[Zaitsev Serg]

Are there anybody knows is there way to get working classles in-addr.arpa zone in BIND 9.1.1rc4 ?
All working OK, even in-addr.arpa zone, but only in class mode, in classless does not.
I could not find a way to power BIND 9.1.1rc4 running reverse zone for /28 net.
Who knows how to?
