There is no need to use any binary drivers on the nForce4 - the only
ones even available are for the network and audio. The network works
fine with the forcedeth driver included in the kernel - I don't know
about the audio, I'm not using the onboard sound.

Some wrinkles with Linux support are that you may need to update the X
server (ex: X.org) as there are some bugs with PCI Express video on
x86_64 that were fixed somewhat recently - as well there was a bug with
USB port detection that cropped up in kernel 2.6.10 and I believe is
fixed in 2.6.11.

The nForce4 chipset supports NCQ on the SATA interface, however this is
not supported in Linux yet. It seems like the SATA controller has some
similarity or is based on the ADMA architecture (the Windows driver is
called "NVIDIA nForce4 ADMA Controller", so using it with the ADMA
driver might be doable at some point, though I haven't heard of any
hardware specs being released..
