I'm trying to work out if my GeForce4 card is working correctly or not. I
think I've set it up correctly but NVclock reports the following

AGP status Disabled
Supported AGP rates 1X 2X 4X
AGP rate -
Fast Writes Disabled
Sideband Addressing Disabled


Here's my /etc/modules.d/nvidia file

# Nvidia drivers support
alias char-major-195 nvidia
alias /dev/nvidiactl char-major-195

# To tweak the driver the following options can be used, note that
# you should be careful, as it could cause instability!! For more
# option see /usr/share/doc/nvidia-kernel-1.0.7664/README.gz
#
# To enable Side Band Adressing: NVreg_EnableAGPSBA=1
#
# To enable Fast Writes: NVreg_EnableAGPFW=1
#
# To enable both for instance, uncomment following line:
#
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1



and I've added these lines to xorg.conf

Option "NvAGP" "1"
Option "AllowGLXWithComposite" "true"
Option "RenderAccel" "true"

I get the NVidia logo displayed and glx gears seems to work so I can
safely say that the acceleration is working to a degree and the nvidia
driver is working but how can I be sure that the NvAGP, fast writes and
sideband addressing is working?
Any suggestions?

Try these:
cat /proc/driver/nvidia/agp/status
cat /proc/driver/nvidia/cards/0

nvclock might be wrong, I suppose . Check whether your frames-per-second
score in glxgears is appropriate for your card model, by googling.

Read up on "NvAGP", and set it to 2, and enable support in the kernel.

Looks like something is wrong

athlonxp fred # cat /proc/driver/nvidia/agp/status
Status: Disabled

AGP initialization failed, please check the ouput
of the 'dmesg' command and/or your system log file
for additional information on this problem.

athlonxp fred # cat /proc/driver/nvidia/cards/0
Model: GeForce4 Ti 4600
IRQ: 18
Video BIOS: 04.25.00.27.31
Card Type: AGP

dmesg reports

NVRM: not using NVAGP, an AGPGART backend is loaded!

Am I right is assuming that AGPGART is being used instead of NVAGP because
I have set something up wrong in my kernel? Can I not just opt to use
NVAGP instead or do I have to edit and re-compile my kernel?

Are you using nvidia-kernel?

If kernel developers were diplomats, we'd all be nuked by now...

Well I edited xorg.conf to use nvidia instead of nv if that's what you
mean

# Device configured by xorgconfig:

Section "Device"
Identifier "GeForce4Ti4600"
Driver "nvidia"
Option "NvAGP" "1"
Option "AllowGLXWithComposite" "true"
Option "RenderAccel" "true"
EndSection


and emerge nvidia-kernel worked. I get the nvidia logo when x starts so I
think this is fine.

Yes, that's absolutely correct, that's how you know it's the right
driver.

"zless /usr/share/doc/nvidia-kernel-ver/README.gz". Press
"/" and search on NvAGP (case-sensitive).

Sounds like you should set it to 2 or 3, not 1.

You will need to compile AGPGART as module and then see to that it's not
loaded before you load the nvidia driver with NVAGP, or you could compile the
kernel without AGPGART to be sure to use NVAGP. This means you need to
recompile the kernel if you already have built it in if you want to be able to
use NVAGP. This you can read in the nVidia readme and you will see if your
mainboard has some problems with AGPGART or NVAGP too.
