Gentoo amd64 on nVidia 8200, 8300, 780a or AMD 780G

Installation of Gentoo amd64 on nVidia 8200, 8300, 780a or AMD 780G chipsets.

Has anyone installed Gentoo amd64 successfully on motherboards with the above chipsets, and the disk controllers in SATA AHCI mode?

I am thinking of bying one and put a Phenom B3 stepping 9x50 on it.

Also about ethernet interfaces:

Most of the above motherboards either have a Realtek 8111 PCI-e interface, or use the nVidia chipset one with an Atheros PHY.

Are the above supported?

And regarding the Atheros PHY, what does that mean?

I am going to use the nVidia forcedeth module or the Atheros one?



PS: I am also going to get 8GB of RAM.

I think this would not be a problem because I can configure the amd64 kernel with a flat memory model.

PS2: Regarding Phenom:

Does the existing powernow-k8 supports it, for CPU throttling with cpufreq?
