As I recall it X-Windows has support for at max 5 buttons (note that the scrollwheel is 2 buttons in one, MousewheelUp and MousewheelDown). This gives you a standard config with 1 Wheel, 1 PressWheelButton and 2 regular buttons. Hopefully there will be support for more buttons in next version of XFree86.
Your mouse has 11 buttons as I see it (If the wheels are clickable aswell).
Ive read some about this since I own a couple of mice with sidebuttons and I want to use them along with the standard config as mentioned above. Ive seen people taking about configuring new software buttons to the rest of the hardware buttons but I haven got it to work myself. As for now I use scripts to change my mouse config when I am playing games and I need the sidebuttons more than the wheel.
Hopefully someone has a solution to the binding of more than 5 buttons at once.

And there seem to be a thread in this forum with more info on how :
