I'm closely following this thread, since I'm also trying to make my wifi card to work under Alarmz. Please let us know if you'll manage to make it work. On my Akita, even with the orinoco driver blacklisted and lsmod orinoco confirming that it has not been loaded, iwlist wlan0 scan still returns no results. My card has the 1.8.4 firmware, I'll try to flash the 1.8.2 one and see if it makes any difference.
