Tested pressing the wheel down using 'xev'. Where I would normally expect 
button 2, it completely ignores any buttonpress.

'xmodmap -pp' lists buttons 1-12 (as already stated and the same as 
(sometimes) evdev).

Neither produces any output or changes anything in the way 'xev' reports 
anything. Yet alone getting the middle button (i.e. button 2) to work out of 
the blue.

The synaptics touchpad on my laptop also has a left-right scroll and I've 
tested both using the same apps as well as 'xev' and the thing is that the 
Synaptics driver (as probably most do) uses the scrolling sequence "4 5 6 7" 
(for "up down left right"), while this mouse shows "4 5 7 6" — i.e. the left 
and right scroll buttons are switched/mirrored.

I have no problem finding it, but binding it gives me problems ;)
