I found this bug trying to play Supreme Commander with dual screens enabled and then switching SLI to play FEAR.
After installing the 97.92 Win XP driver, I configure the monitors separately to run at their native resolution. Reboot. Then enter the control panel to enable SLI. Clicking apply to enable SLI causes the screen to flash a few times on the primary display and then both monitors come back on, SLI is still disabled. Reboot. The system comes on with only the primary display active. Trying to enter the NV CP causes it to crash before it can load. By running 3D Mark 06 and seeing the FPS displayed I can tell that SLI is enabled but can no longer make any changes in the NV CP or re-enable dual screens in Windows display manager without un-installing and re-installing the drivers.

NVIDIA is looking into our issue, thanks for the quick response guys!
