It is related, and yeah, I'm pretty sure they dump it. I haven't heard
anything back since reporting the problem about a week after their
latest drivers were available. (Took it that long to isolate their
driver as the culprit. The oops'es were unpredictable and I still
haven't found what the actual cause is.)

Redhat (mixed up versions, I handle my own tarballs) with 2.4.18.
I didn't try the nv driver though. I tried it to start with and had
some problems I don't remember specifically at the moment.
FWIW I had the same issues.
The problem I had was that it would crash kswapd with the following

This vanished when I backed down to NVIDIA_kernel-2314.
No big loss to me except I miss the loss of DigitalVibrance.
If only I could grab the source I'd backport it, and alas my asm
(especially gdb disassembling it) is pretty rusty.
