It works, in that the machine no longer panics when I try to frob ndis0 directly. I can still create a wlan0 on top of ndis0, and this appears to send and receive traffic properly. I can assign ndis0 an IP address and netmask with ifconfig, but ifconfig ndis0 scan is ``unable to get scan results''. (I also can't give ndis0 an ssid (SIOCS80211: Invalid argument), and thus can't send traffic directly on ndis0.) I also got some error messages when I had given ndis0 my static IP, added wlan0 on top of it, and then tried to send traffic. My understanding is that this is not a supported operation, though, so I won't worry about it. Let me know if you want more information/testing. Thanks, Ben Kaduk
