I've just submitted a rt2x00 patch that registers a valid address mask with mac80211. So, you could actually use this information to generate valid MAC addresses for this device: /sys/class/ieee80211/phy0/macaddress /sys/class/ieee80211/phy0/address_mask However, I'm not sure if other devices behave the same or not. So using this approach might not work for other devices ...
