I do not think that you need to be ifconfig'ed to talk to the packet capture mechanisms on Linux. Just go read netif_rx() and netif_receive_skb() in net/core/dev.c. So long as you can call with an skb, you are probably set.
So what mechanism prevents packets received promiscuously from going to sockets other than PF_PACKET sockets? They'd probably want to use that mechanism, as those packets presumably aren't supposed to go to, for example, the IP input stack.
