I got FC4 to install using the Silicon Image SATA controller and an IDE
CDROM.  I also inserted a PCI 10/100 card to get network support.  After
installing FC4(or any distro for that matter), edit your inittab before 
you reboot and set it to boot into run level 3.  Once you have rebooted,
you can run an update(via yum) to get the latest kernel and Xorg stuff.
This allowed me to boot the machine into level 5 and my video card did
function(NV 6200).

Indeed, ASUS is kind of "sucking" in the tech support realm on this
issue.  I have been poking around with "dmidecode" and "lshw" and found
some really interesting stuff.

I am assuming that this is causing some kind of weirdness that disables
the use of the NV SATA, USB, Sound and the Broadcom ethernet device.
Any ideas what the "OUT OF SPEC" warning actually means?
