I dug around in the gnustep-back and figured it out myself.

That's exactly the hint to the problem. Here's what happens and why nobody 
else was able to reproduce the bug:

On my ThinkPad I have two pointer input devices configured: one is the mouse 
knob on the keyboard and the other is the USB mouse. When the backend comes up 
it sees the mouse knob first which identifies as having only 3 buttons -> 
mouse wheel support won't work in the backend.

As a workaround I've added "Options Buttons 5" to my X config and now the 
mouse wheel works :-)

Still thinking about how to cleverly fix this ...
