1284P Servo Library on Timer 3?

I'm going to use the mighty core on the 1284P. I don't have the chip yet. Does anyone know if the Servo library will use Timer1 or Timer3? Is there an easy way of making it use Timer3? I'm using SPI and it covers up the Timer3 PWM pins, so if I'm losing them anyway it would be nice to not also lose the ones on Timer1.

I'm going with "probably Timer3".
