OSPF debug (packet, event) showed no incoming OSPF packets. The 2-3 neighbors that did come up on the 7500 were in FULL/DR, FULL/BDR, and 2WAY/DROTHER (from memory; I was more interested in getting the device up rather than capturing details).
One thing I was thinking of was that the physical port was dropping incoming multicast for some reason.
