I have tried 2 wire X10 wall switches with CFL type bulbs. They do not work since the switch steals power through the load.
3 wire wall switches ;line; load and neutral; not a three way with line; load and traveler; may work. Depending on the bulb in question and the model switch used. I have tried a CFL and a Insteon dimmer as a test and if the ramp rate is set to high on and off seems to be fine.
Non dimming X10 switches with a real neutral wire and a mechanical switch should also work.
