Does anyone have an easy fix that will allow me to assign keystrokes to my MX510 buttons ?

I have a new gaming lappy (Rock Core 2 Duo 2.33, Go 7950, 2 gig RAM 200 gig HDD ..etc) and the performance is great but I can't figure out how to map keystrokes to my mouse.

On my desktop it is easy - install mouseware and via control panel -> mouse click on buttons tab

On the laptop however the buttons tab has settings for the synaptics touchpad ... grrr

I have seen a few convoluted methods that involve installing old synaptics drivers but wondered if someone had an easy method ?
