Abit kv7-v motherboard with via kt400 chipset, AMD2800+ processor, 1 gig memory, slack 10.1 using 2.4.29 kernel.

I've pretty much got slack linux going, even getting the "nvidia" splash screen when envoking startx. However, during boot, I've still got errors for agpart. I'm wondering if this part is the problem.

In sbings slackware faq section for nvidia, he says to edit usr/src/nv/os-registry.c for tweaking via chipset as follows:
*static int NVreg_EnableVia4x = 1;
*static int NVreg_EnableAGPSBA = 1;
*static int NVreg_EnableAGPFW = 1;

And the os-registry.c file has this entry:

* You can enable any of the registry options disabled by default by
* editing their respective entries in the table below. The last field
* determines if the option is considered valid - in order for the
* changes to take effect, you need to recompile and reload the NVIDIA
* kernel module.

nv_parm_t nv_parms[] = {
{ "NVreg", "VideoMemoryTypeOverride", &NVreg_VideoMemoryTypeOverride, 0 },
{ "NVreg", "EnableVia4x", &NVreg_EnableVia4x, 1 },
{ "NVreg", "EnableALiAGP", &NVreg_EnableALiAGP, 1 },
{ "NVreg", "NvAGP", &NVreg_NvAGP, 1 },
{ "NVreg", "ReqAGPRate", &NVreg_ReqAGPRate, 0 },
{ "NVreg", "EnableAGPSBA", &NVreg_EnableAGPSBA, 1 },
{ "NVreg", "EnableAGPFW", &NVreg_EnableAGPFW, 1 },
{ "NVreg", "SoftEDIDs", &NVreg_SoftEDIDs, 1 },
{ "NVreg", "Mobile", &NVreg_Mobile, 1 },

{ "NVreg", "DeviceFileGID", &NVreg_DeviceFileGID, 1 },
{ "NVreg", "DeviceFileMode", &NVreg_DeviceFileMode, 1 },
{ NULL, NULL, NULL, 0 }

Now, how does one properly edit the above? I'm not succeeding recompling this following the instructions. I seem to get a little further when using "./nvidia-installer -k 2.4.29", but no dice. Any help will be appreciated.

What is your video card ?

(Also the changes seem already applied)

I had a little play with FREEBSD a while ago. I cannot confirm this, but when using Nvidia, it was best to use AGP provided by Nvidia not the one provided by the install. Whether this has any bearing for your setup...... I don't know. Something to keep in mind if you come to a dead end :-)

Video card is gigabyte geforce 6200.

I should have been more specific. Dmesg reports it recognizes the memory and chipset for agpgart. The problem is agpgart is "unable to determine aperture size". It say to "see README section for cache aliasing for more info". Now where would that be?

Look at /usr/doc/NVIDIA_GLX-1.0/README.txt

But at Cache Aliasing section, there are no much infos, they
just suggest update the kernel...

After some googling, it turns out 2.4X kernel apparently doesn't support 8Xagp for kt400. I compiled the 2.6.10 kernel and enabled via chipset support, and it does solve the problem. But, now I'm having problems with sound, dialup, etc. which will be handled in another thread, if I can't solve them.
