I have done this several times, across multiple installs on my desktop, laptop and work computer.
The Mad Catz R.A.T.7 is a great mouse that I bought on a whim not because I’m much of a gamer (I’m not) but because it fit my hand and I felt a pang of Retail Acquisition Syndrome while looking at the damn thing. It turns out that the selectable DPI setting is great for switching between a Linux desktop machine and the OSX at work. I could never get the standard acceleration setting in OSX to behave like I wanted, but turning the DPI down in hardware on my mouse worked great!
