I had the same problem of getting my iwl4965 to associate to various access points. By accident I noticed that "iwconfig $dev ap any" did trigger that process (I now read that essid works as well). I created a script that hooks into if-pre-up.d and waits for the wireless interface to come up. That way, the connection will be ready when dhcpclient comes along. I also included a triggering mechanism that tries to force reassociation when no access point is found. After a timeout of around 10 seconds, the script passes on, whether an agreement with the ap could be reached or not.
I attached the script to this mail and uploaded it to http://wertarbyte.de/debian/wireless-tools-snooze I hope it helps :-)
