[rescue] Quick/Easy way to test Sun mice?

[Steve Hatle]

I got a pile of Sun mice (both roller and optical) from a friend who 
picked them up in a deal and wants me to test them for him.

Is there a quick and easy way to test functionality (x,y movement, 
button presses) without having to shut down and restart a machine into 
X/CDE?

Are Sun mice hot swappable? I can't find any reference either for or 
against. Don't really want to try it out on any of my machines if the 
answer is "NO!"
