Not exactly what you're asking (dunno about the mouse wheel), but I use
this hack to scroll text without getting the cursor off the center of
the screen:

,----
| ;; "smooth" scroll
| (defun guti-scroll-up (cuenta)
|   (interactive "p")
|   (move-to-window-line nil)
|   (scroll-up cuenta)
|   (forward-line cuenta)
|   )
| 
| (defun guti-scroll-down (cuenta)
|   (interactive "p")
|   (move-to-window-line nil)
|   (scroll-down cuenta)
|   (forward-line (* -1 cuenta))
|   )
| 
| (global-set-key (kbd "C-<") 'guti-scroll-down)
| (global-set-key (kbd "C->") 'guti-scroll-up)
`----

HTH,
