Linux WiFi driver

• The Madwifi driver works with this adapter.
• LEDs might not light up: see http://madwifi.org/wiki/UserDocs/EnableLEDs

Madwifi driver works fine on R51e, but the antenna seems to stay switched off after suspend to disk and cannnot be activated without a reboot. Somewhat annoying, shutting down the device before suspend to disk does not solve the problem.
