Normal when housing seals are going. Smoke is from water that is laying in bottom of rotor chambers.
On early stages of failure there may be no indication during running. What happens is that when you shut down there is still 14psi in the cooling system 0 in the rotor chamber, weak seals or warped housings allow pressures to equalize, putting water into the rotor chamber. Which is what you see burning off when you start it.
Very small amounts of smoke can be normal, but you can usually tell that it is steam from condensation build up in the exhaust, especially in damp climates.
Check for engine seals by toping off the cooling system, leave the cap off and start the car. Watch for bubbles. There will be some rising of the coolant as it warms up. Put a catch pan under the vehicle.
1st sigh is very small bubbles, tiny, one could say they look like dust particles.
2nd stage they form a foam like substance.
3rd stage, larger bubbles that have gray smoke in them
4th stage, blows the water out like a geyser.
On the early stages of failure you may have to let it run until it gets to full operational temp.
You can baby it through the winter by relieving the pressure when you shut down.
If you lived out here in the southwest desert I would be telling you that it will not make it through next summer.
Afraid it is time to start packrating your pennies.

Not out of the exhaust. If you let a rotary sit you'll get a little smoke, especially when it's cold. As long as you don't get smoke during normal driving (after warmed-up of course), or smoke @ high RPM, then everything's kosher.
But get that belt replaced, and keep an eye on your voltmeter.
