tux racer owns!
i don't know about the mouse drivers...my logitech is three buttons, but the scroll wheel doesn't work...but if you press the scroll wheel down on the desktop a menu pops up..hmm i haven't checked the logitech site yet. good luck with your mouse, but chances are if you didn't set it up right during installation you might not get all 5 buttons to work.

edit: this is probably what you'll find: (from the logitech website)
