Would this help?  :

20041219:
        Auto-loading of ancillary wlan modules such as wlan_wep has
        been temporarily disabled; you need to statically configure
        the modules you need into your kernel or explicitly load them
        prior to use.  Specifically, if you intend to use WEP encryption
        with an 802.11 device load/configure wlan_wep; if you want to
        use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
        and wlan_xauth as required.
