I am pretty sure that the hardware PWM in the Arduino is too fast to
control a servo.
Do you have the specs for the PWM signal that you need to send to the
servo? This actually reminds me, this might be an application of
[pwm], since servos actually need pretty low frequency PWM signals to
control them, like 50 Hz or so IIRC.
