Control many leds using Pulse-Width-Modulation?


i want to dim 25 LEDs using the FEZ Hydra. My first idea is to
buy a couple of load modules and toggle the channels off and on very fast
to achieve some Kind of pulse-width-Modulation. I want to have a PWM-Frequency
well above 120 Hz to avoid flickering. Is this even possible?
If not, what is the frequency with which the GPIO-PINs on
the board can be switched on and off?

If the Hydra is not capable of this, is there another .Net-Gadgeer-Board that is?

Why not connect the gadgeteer hub and then you will have many pwm pins
