I think you'll find that RFC 2022 for multicast support and the ARP support described in RFC 2225 should both apply, then. Because when these RFCs were written, ATM did not yet support point-to-multipoint addressing intrinsically. So any protocol which depends on multicast addressing had to emulate this feature, which they did by implementing dynamically updated lists of unicast ATM addresses. That is, for unicasts, the address resolution part of the puzzle should be solved, even if the ultimate end-to-end link won't be direct. For multicast, I think the fit is pretty good. Parenthetically, multicast addressing support was introduced in ATMF UNI 4.0 for awhile, then deleted again. Amazing. As far as I can tell, none of the RFCs that might have made use of multicast addresses was ever changed to capitalize on the new feature, not even in I-D form. Interest had waned quite a bit by then, late '90s. Maybe that's why the ATMF deleted it.
