You've answered the inverse of my question :) to clarify my rather bulky 
paragraph in the previous mail,
if:
 * the NIC is in promiscuous mode, and
 * you receive a packet /p/, and
 * the MAC address in /p/ is _not_ yours, and
 * the IP address in /p/ _is_ yours,
what do network stacks (not NICs) typically do? Do they respond to the packet 
in any way, or do they understand that because the MAC is different it should 
be ignored? I expect that is what they should do, but I'm curious if it is 
actually the case.
