There is no smooth scrolling when using the EmulateWheel feature

On a machine with a touchpad (using, i guess, synaptics driver), scrolling by sliding the finger at the right of the touchpad produces smooth scrolling (that is, if i only do a tiny movement i only get a scrolling of a few pixels instead of a whole line) in softwares that support it like nautilus.
One would expect that the option EmulateWheel of the evdev driver (used on a trackball without scrollwheel) produces the same effect, since it's all about scrolling being produces by an analogical source instead of being produced by buttons 4 and 5.
