Problem loading nvidia drivers on SN41G2 w/ RH9

Has anyone updated the nvidia linux drivers on SN41G2?

I've put my system together last month and have been able to get dual-boot
XP and RH9 loaded without any problem. XP works perfectly including eth0.
RH looked great until I tried using the built-in network card. Ended up at
nvidia's site and in total confusion with two updates, audio/network/GART
(...0261...) and graphics (...4363...).

Have made several attempts including using the home-brew network driver that
was posted in the nvidia discussion groups. This actually worked for
getting the network card working but fouled up when I later went in to do
the RH auto-update. So started over, again, and again...using the release
notes and rpm at:

http://www.nvidia.com/object/linux_nforce_1.0-0261.html

Here is where I am now:

a) loaded RH9 (2.4.20-8)
b) then did the RH auto-update to 2.4.20-19.9
c) then nvidia's update -- rpm NVIDIA...0261.rh90up_2.4.20_9
d) am not sure I need to do the GART update with the rpm but gave it a try
anyway. Was not able to do the GART patch on the last because following the
instructions there is no linux-2.4.20-agpgart.diff in a
/usr/src/linux-2.4.20 or the two directories (...2.4 and ...2.4.20-19.9)
that I do have.

Hoping the GART patch only affects the agp I am not using, went to network
configurations and the nvnet hardware is now visible but when I try to setup
the device, it says the nvidia card is not working. Shutdown and restarted
as there is a note saying the modules must be started. Still cannot create
the device.

Questions:
Do I need the GART patch and, if so, where should I look for the patch?

or

What else have I missed?

Appreciate your help.
