FYI, the Mouse System A3 seems to work just fine under 2.1.  All three buttons recognized in X!  A fully-functional, optical, 3-button, ADB mouse - kind of the holy grail of mac68k-dom.  :)  Just don't lose the special mousepad...

I also recently tried the Kensington Turbomouse (trackball) and Interix (sp?) MAC-100.  Both are two-button devices, and gave basic functionality (pointing and left-click), but the right-click was not recognized.  I did not get a chance to try out my Macally 2-button mouse.
