Yep, that's the problem. 2.4.7 doesn't have a clue how an nForce motherboard works. You might be able to use VESA video, then install the nForce drivers from nVidia, but I don't know for sure whether those include an AGP driver or not. They may not.
If they don't, then the first order of business would be to find a kernel (if there is one) that works with nForce AGP. I'm not convinced that there is one, actually... which might be bad.
If you can at least get a system up, then you might be able to get the nVidia video drivers to work with NvAgp set to "0" -- AGP disabled.
