FYI, I fixed up the OZ wlan-ng handling a bit. You can now configure it via /etc/network/interfaces, similar to the way one configures the usual wireless-tools interfaces. Naturally the gui doesn't handle that yet. I'll write up a page on the wiki describing how this configuration works.
I also adapted the interfaces entry to automatically do the necessary bits (load module, enable the hardware) on up, and the reverse on down. So, you can now use the GUI network application to bring the interface (wlan0) up and down, and it will properly do so.
