I'd be nice if someone could test it with a real fan, though. Sure, if someone has a vt1211-based board that actually has the fan connected to the PWM output. I haven't seen one yet... And sometimes I'm wondering why do I put so much effort into implementing PWM if none of the VIA boards actually uses the PMW outputs? sigh... > The driver should provide the functions the chip provides.
