Those logs are too long for the mailing list, as told by IRC I've 
sent them to pastebin.ca. http://www.pastebin.ca/576578 is the 
successful association, http://www.pastebin.ca/576582 is the 
unsuccesful one.

I think we have an authenticate-reauthenticate problem. When I 
turn the laptop off and start it (which takes a while), then I'm 
always authenticated to the AP.

But when I do

    # pccardctl eject; sleep 0.5; rmmod libertas_cs libertas
    # pccardctl insert

Then I almost always can't associate. When I first remove, then
wait 30 Seconds (or de-authenciate the station manually from the 
APs configuration web site), then authentication at card 
insertion time works again.

Note that other cards don't have this bug.

I'll look if I find something "in the air", about different 
behavior of different cards.
