As mentioned on the linux-wireless mailing list, the current copyright statements in the rt2x00 are meaningless, as the rt2x00 project is not even a formal legal entity. Therefore it is better to replace the existing copyright statements with copyright statements for the people that actually wrote the code. Note: Updated to the best of my knowledge with respect to who contributed considerable amounts of code.
