The driver already mapped the middle and right buttons. Since the single mouse-button on my Apple laptop broke, I figured the driver might as well support all three buttons. Now I can keep using my laptop without problems. The patch is against 2.6.31. John Ogness (I do not belong to either linux-input or linux-kernel mailing lists, so please reply directly. Thanks.)
