Incorrect, at least on FreeBSD tcpdump will show packets if card is not associated. Note that such packets doesnt have anything with tcp, ip and other (IPS) *higher* protocols. So in short tcpdump allow monitor of 802.11 packets.
Didnt tried same thing with OpenBSD, but probably pcap(3) plays some role in this.
