Yes, or so I think.

Mouse scroll can be set from X server as well as per application basis, 
that is, you can set Xorg to use a value (e.g., scroll 3 lines at a time) 
that will be used system wide affecting all of the programs but you can 
also set a different value for one application which will affect just 
that app. Firefox, for instance, can be configured to use a different 
mouse scrolling value so I guess there can be others... I don't know for 
OpenOffice, though :-?

There you have it. So the question is now how to instruct that driver 
(evdev) to use a different scrolling value, I see nothing at all a the man 
page nor in the docs :-?

Yep, there is not much information on the matter or at least I was unable to 
find a clear way to configure it. 

I would ask this question directly at Xorg's users mailing list:
