Unhappy Lockups due to AGP card disabled?

I've been experiencing lockups using Mandrake 9.1 (Fresh install with latest updates and kernel) while trying to run UT2003, and after lots of research on the web, I was able to query this information which shows that may AGP GeForce TI4600 AGP 128MB is not running in AGP mode.
If that's the case, how do I get it to work in AGP mode?

Motherboard: ASUS A7A266 (Please see the reports below for additional
information. Thank you...

From the README:

Quote:
On ALi1541 and ALi1647 chipsets, NVIDIA drivers disable AGP to work around timing issues and signal integrity issues. You can force AGP to be enabled on these chipsets by setting NVreg_EnableALiAGP to 1. Note that this may cause the system to become unstable.

I have already tried disabling AGP on XF86Config-4, but the system keeps locking up...


How do I configure NVreg_EnableALiAGP 1 ?

Thank you...

AGP is already disabled -- there is nothing you can do in XF86Config-4 to disable it if it's not running!

Passing that option to the nvidia kernel module will also not get you any stability -- it'll probably cause more lockups. The snippet of the README that I posted was explaining why your AGP was disabled in /proc/driver/nvidia/agp/status.

About your other questions that I missed before:

Quote:
PCI Controller... Is this correct?
Most definitely correct. The only difference between AGP and PCI is that AGP has faster access to parts of the system memory. They are, in the end, exactly the same bus.

You should neither have a /dev/nvidia nor a /dev/nvidia1. You should only have a /dev/nvidia0, assuming your distro uses devfs.

Are your lockups happening with a DVI-connected monitor? If so, that's probably the cause -- the nVidia drivers are having issues with DVI. Hook the monitor up with a VGA connector (or DVI->VGA converter, that works too) instead.

=> Yes I do have /dev/nvidia0. Sorry, may mistake while typing.

=> I only have a regular VGA Monitor using the VGA Connector.


After tweaking the system, now the lockups occur just as the game (only tried Single Player Mode) is about to start. Before it used to crash during the nVidia Logo.

X runs ok...


Thank you...

System Still lockig up under UT2003. I have tried all combinations and still locks up.

Any more ideas???

Do I need to recompile my kernel not to use ACPI?

HELP!

That might help, I don't know... while you're at it, I think you can turn off all the APM stuff too, except for "console blanking" and the main APM setting (you need the main one to be able to shut the computer off after shutting down, in runlevel 0).

Try disabling dga.
Maybe it is solving your problems, maybe not.

Have a look into you XF86Config.
Search for this lines:
SubSection "extmod"
Option "omit xfree86-dga"

If the Option line is missing, place it directly in the line beneath the extmod line

disabling dga didn't help either.Just in case, I added the End SubSection command to close the subsection, otherwise X wouldn't start.
Any other ideas?
Should I leave the Videocard working as a PCI card instead of AGP or should I force it to work in AGP mode?
Should I disable DPMS in X?
Should I use AGPGART or Nv_AGP?
:'(

It's been over a week and can't figure out how to solve the problem. In the meantime I was able to help 4 other new Linux Users, but can't help myself!!!!
