It seems that the acces point is found but that association doesn't succeed. I had that I use TKIP as encryption method. I just wanted to know if this is a known bug of the driver or of wpasupplicant and we may hpe that it will be solved when the final release of the 2.6.13 will be released.

It looks like your build of the ipw2200 doesn't suport that WPA
interface. There can be two reasons:
1 -  Your kernel's .config has CONFIG_IPW* and CONFIG_IEEE80211*
definitions which you must remove;
and/or
2 - Your kernel has support for wireless extensions version 18, which
probably disables the old WPA interface (wpa_supplicant's driver_ipw)
and enables the kernel WPA interface (wpa_supplicant's driver_wext).

Check [1] and if it still doesn't work, then check [2] by trying to use
wpa_supplicant with -Dwext instead of -Dipw.
