There are 3 ways a wireless card can run. (Not counting ad-hoc, but
that's irrelevant.) The "normal" way is for it to talk to an access
point and pass only packets destined for it to the OS. "Promiscuous"
mode (often confused with monitor, but not the same thing) comes from
Ethernet and will pass all packets on the network to the OS. "Monitor",
or "rfmon" mode will pass all raw 802.11g packets to the OS, allowing it
to see traffic from any network, encrypted or not (obviously it can't
decrypt encrypted traffic, but it will pass it on nonetheless). The
reason for the distinction is that on 802.11, the traffic on one network
(promiscuous) is not the same as all traffic received (rfmon), while on
Ethernet you only receive traffic on one network, so they are the same
thing.

And, no, ipw2200 doesn't have rfmon. (Yet.)
