Uncomment this line in your XF86Config

#    Option     "ZAxisMapping" "4 5"

The imwheel port is more or less intergrated into the X11 since 4.2. I 
dont have it installed and the wheel works great in X11.

You must use the device /dev/sysmouse in X11 if you run moused on the 
console.  If you disable moused on the console you can use the device 
/dev/psm0. I suggest you get rid of moused to simplify the troubleshooting.

Do check (#dmesg | grep psm0) what your mouse is being seen as by the 
kernel. I get flakey issues with my KVM that made my mouse into a 
generic ps2. You might need to change a flag on atkbd and rebuild the 
kernel.
