Hi... I'm interested in building a low-power server using the 780G or 790GX chip.

There's a lot of marketing info about the power-saving features of this chip. However, I'm wondering how well they are supported in Linux.

If the power-saving features are Linux-supported, how are they supported? Open-source driver? Proprietary AMD/ATI driver?

My experience with using PowerPlay on my laptop with ATI graphics hasn't been too great; it required the use of the proprietary driver. Also, if I remember correctly, interfacing with that driver required X to be running, which doesn't make sense for server whose display will only be using during setup.

Anyone know the details?
