Eli,

I have such a mouse plugged into a PS/2 port.

I do not know how to confirm or deny that observation.

I can certainly confirm that, though. I can draw down the menus
in emacs 20.5 with both of my real mouse buttons, but there is
no response to wheel events.

And you are, for example, unable to navigate a directory structure
using dired using just the mouse. Me too. Yuck!
