Sorry if this duplicates, replied from wrong address:

$ grep middle /var/log/Xorg.0.log
[     6.938] (**) Primax Kensington Eagle Trackball: Applying InputClass "middle button emulation class"
[     7.089] (**) Primax Kensington Eagle Trackball: Applying InputClass "middle button emulation class"

So I think X is seeing my modification.  Haven't added evdev.
