Hi,

I also have a 3650 HD in my laptop and I found that once I modprobe fglrx (the
proprietary driver from ATI for Linux), the fan noise is considerably reduced
and the behavior of the GPU/fan (on/off) is the same as when running Windows
Vista. That's fglrx is properly switching between the various PowerPlay tables
once loaded.

Having PM support (into any radeon driver) and documentation released to the
developers is a mandatory (not optional) step to support users who chose to buy
AMD's chips. PowerPlay is part of the product, the end-user bought, and not
having it means that he can't enjoy the full utility of the said chip
(eventhough the end-user paid the price for it) because of a potentially
reduced chip lifetime, especially for laptops. I think that PowerPlay support
as much important as any other functionality such as 2D and 3D acceleration and
I for one, really hope that AMD will take the right decisions and provide the
much needed documentation.

Regards,
Ilyes Gouta.
