more info needed.

i have the same card.

it works here with the madwifi-ng svn and wpa_supplicant cvs from a hour ago.

so keep with cvs/svn HEAD versions.

im just trying to reproduce the driver oopses on autoreset and in the processtriggers function / hal  
i had for the last days. i thought the card was damaged but it works fine so far.
im waiting for the autoreset on hw error.

no issues so far only a ioctl[unknown???] warning with wpa2-enterprise connected to 0.4.7 hostapd 
running madwifi-old.
