If you see them in tcpdump without promic mode, then the card was receiving

I guess the network
stack is recognizing them as packets for "otherhost".

I dont think its a NIC problem if you see the packets in tcpdump-

The promis is receiving the packets, but it is not processing the packets
which are not targeted at the own system with the normal IP stack. I am not
sure where you can add the additional MACs to make them beeing recognized.
