Mine reads:

Section "InputDevice"
         Identifier  "Mouse0"
         Driver      "mouse"
         Option      "Protocol" "auto"
         Option      "Device" "/dev/sysmouse"
         Option      "ZAxisMapping" "4 5 6 7"

This may have been atomatically generated, but I'm not 100% sure since 
this has been working for years.

"default desktop" meaning twm? If so, is it working *now* with twm? If 
so, this looks like a gnome issue, on which I am not qualified to 

I'd first try eliminating the gnome variable: in your xinitrc, comment 
out whatever it is that starts gnome and replace it with <some other 
window manager> instead, perhaps twm, and see if the mouse works. Then 
you'll at least know if it's a problem specifically with gnome, or with 
X in general.
