The trick is to find a fan with a single speed. Multiple speed fans use differamt taps on the windings to get the three speeds. You might try setting the fan on high then use the X10 control. Fans with built in variable speed controls don't use tapped windings. Not sure but those fans (I don't think) even use a shaded pole motor which might be the problem. I have a single speed ceiling fan in a box not installed yet and when I go to put it up I will try and see what type of motor it has. Hope this info might help a bit.
