Alright, here's the scoop.
Slackware 9.1. Kernel upgraded to 2.6.5-mm6. X upgraded to 4.4.0.
The machine is an HP Pavillion a320n, which seems to have an nforce2
Installing the driver with the .run file works fine. A module gets
compiled, installed, and I can 'modprobe' it just fine. There are no
unresolved externals; it shows up in my 'lsmod' data. I edit my
XF86Config file to change Driver "nv" to Driver "nvidia". I've toyed
with different AGP settings, IgnoreDevices settings, etc. But every
time I start X with "nvidia" ("nv" works FINE!), the screen goes black
and I get a complete and total lockup. No keyboard, no network,
zippo. Earlier postings said that X comes up after a few minutes,
but not in my case. The only thing I can do is a hard reset.
The /proc/drivers/nvidia/cards/0 contains:
Model: GeForce4 MX Integrated GPU
Video BIOS: ??.??.??.??.??
Card Type: AGP
Interesting on the video BIOS, huh?? When I boot down into XP, I
can get device properties and it says v.4.1f.00.07.10
I can't get an X log, since the machine crashes and the file doesn't
get written (or committed out of the reiser journal...)
Attached is my kernel config file, in case anything in there looks
suspicious, as well as some startup log info. Thanks for any help, folks!
