Help installing nvidia and X

Question

Hi
new to Linux & Arch, having trouble running X, hoping someone could help!
installed Arch no prob, followed wiki instructions for installing nvidia and then Xorg. When I try to start X I get "Failed to load the NVIDIA kernel module!"
modprobe nvidia
gives an error too
here is my Xorg log and xorg.conf. Hopefully someone can spot what I've done wrong!

Answer 1

cat /etc/X11/xorg.conf| grep Modes
for my xorg.conf, under Section "Screen" I have the following Modes:
Modes "1280x1024" "1024x768"
Modes "1280x1024" "1024x768"
Modes "1280x1024" "1024x768"
Modes "1280x1024" "1024x768"
Modes "1280x1024" "1024x768"
#Option "MetaModes" "1024x768, 1024x768"
Modes "1280x1024" "1024x768"
However, yours is:
Modes "1600x1200_75"
Is that valid?
And what error does modprobe give you?
