[f-nsp] Multicast causing high CPU

Did anybody ever come up with a fix for this? I have some FESX and
SuperX switches doing simple L2 forwarding, and it seems that they are 
CPU switching all the flooded multicast traffic (the default behavior if 
you don't do igmp snooping). I opened a case on this and was told that 
these platforms are incapable of hardware flooding multicast traffic, 
which seems like a serious design flaw.
