(EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module!
(EE) NVIDIA(0): *** Aborting ***
This is your problem. From your nvidia-installer log, it looks like you built the driver while booted into the 2.4.20-8 kernel, not the 2.4.20-8smp kernel. Is this correct? If so, you need to reboot to the 2.4.20-8smp kernel and reinstall the driver.
