Uuggh, this seems to be a serious problem, even when using nvidia.ko.
Why? Because xorg seems to probe drivers on startup, and somehow managing to load the nouveau module even when I want to use the nvidia module. The nouveau module then fails to unload properly (use count is always at least 1, and stays 1 even after changing to runlevel 3 and killing xorg).

I could reliably hang the system just by logging out from kdm. Syslog is full of nouveau problems - why, given that I am using nvidia?
When renaming all instances of nouveau.ko under /lib/modules the hangs disappeared.

This has always been there and seems to have zilch effect:

> ls -l /etc/modprobe.d/nvidia.conf 
-rw-r--r-- 1 root root 18 2011-04-29 22:55 /etc/modprobe.d/nvidia.conf
> cat /etc/modprobe.d/nvidia.conf
blacklist nouveau

Symptoms are random freezes requiring a hardware reset, but always
involving some graphics operation. I can detect no other hardware
malfunction, and lockup behaviour is not characteristic of general
hardware faults (e.g. ram, cpu, disk).

My reset button is really polished now ;-((

System details:
openSUSE 11.4 with all updates installed,
currently that is kernel kernel-desktop-2.6.37.6-0.5.1.x86_64
xorg-x11-server-7.6_1.9.3-15.24.2.x86_64
The problem seems worse with
kernel-desktop-2.6.39.2-36.1.x86_64

01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT
220] (rev a2)

Mobo is Gigabyte GA-880GA-UD3H with
NB/SB: AMD 880G / SB850
USB 2.0 + 3.0, SATA 3Gb + 6Gb (prob not relevant)
The chipset also contains an integrated ATI Radeon HD 4250 (which works fine on the OSS radeon driver, with the limits of the driver).
