4191 crash after card upgrade. 3123 works?!

[olddoc]

I had a Geforce 2 ultra working with 4191 drivers under RH 7.3 2.4.18-18.7.xsmp on a Thunder K7 dual athlon board. I always used the tar files and "make install" to install and upgrade files.
I put in the new card and Kudzu messed up my XF86Config-4 file so I got an old one from backup and tried -- no go. Got a lockup without the ability to ctl-alt-bksp or ctl-alt-del
I finally tried to revert to 3123 drivers: I did a make install for kernel and GLX and I was able to startx!!
I attached my XF86Config-4 file and my log file with verbosity 5. When it crashes, it stops during reporting sub module vgahw.

Can anyone help me get back to running 4191?

This is the verbose5 log from when I tried to startx with 4191 drivers.

Now after a make install under kernel_3123 and GLX_3123 I can startx and get 3D!

What is the conflict that is causing trouble with 4191??

I do not know for sure what the problem is but I have a few ideas about what I would try:
1) remove the DRI section. It is useless and the docs tell you to, I doubt it makes a difference ... but its simple to do so why not.
2) Add a
VideoRam 65536
line to the device section ... it stops just before reportng the video ram size (at least that is next in the working log file) so /maybe/ 4191 has some WeIrD issues with detecting ram size ... at least it can't hurt to try.
3) try other values for NvAGP ... in particular
NvAGP "0"
might be interesting. It looks like the crash is a good ways before an of the AGP stuff, but its worth a try IMHO.
4) Option "NoDDC" "true"
The crash happens just before the ddc stuff so this /might/ help, but I doubt it, but again its worth a try.
