A little late but I have the same problem, screen flickering and sometimes hangs whole computer. Running Fedora Core 6 with latest Kernel. Running a LG-M1 laptop with dual core and GeForceGo 7400.
It reminds me of the good old Amiga when it crached sometime it looked like this.
I'll try the suggested:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
I added the option to: /etc/modprobe.d/nvidia and the screen locked at the loginscreen and only a hard shutdown and removing the option solved the problem, and I have gone back to the nv driver.
Waiting for noveau....
