I have a fancy Logitech G500 (which is odd, because this mouse started as a cheapo MX510 and RMAs made it better and better over the years... haha, Logitech tech support is amazing and I always buy their stuff) and I'm surprised KDE recognizes all the buttons out of the box. I also converted entirely from a Windows-only XP world, to a hybrid Ubuntu / 7 for gaming setup, and now I'm just running Arch only. I always got my pointer acceleration to align perfectly between them. Hell, even the DPI switching on the G500 works. I think it is built into the mouse, though.
