ath + wep issue

Ok, on the ath card the issue seems to be related to the interaction
with the AP and the roaming mode... This problem is exacerbated by the
fact that I sometimes manage to get the card into a state where I can
see outbound 802.11 frames with tcpdump, but never see inbound packets,
i.e. probe responses... Those are the instances when it scans
forever... Ejecting the card and re-inserting gets me back to a useful
state.
This is long, sorry...
This is what happens when I plug the card in and wpa_supplicant tries to
configure the card.

I either have or can provide tcpdumps of each specific case if that
helps more, but I figure this message is long enough already.
Now, off to debug the other issues with the wi card, sigh...
