FATAL: Error inserting nvidia /nvidia.ko

FATAL: Error inserting nvidia (/lib/modules/2.6.16-gentoo-r12/video/nvidia.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg output

nvidia: module license 'NVIDIA' taints kernel.
nvidia: Unknown symbol remap_page_range
nvidia: Unknown symbol pci_find_class
nvidia: Unknown symbol remap_page_range
nvidia: Unknown symbol pci_find_class
nvidia: Unknown symbol remap_page_range

I'm using kernel-genkernel-x86-2.6.16-gentoo-r12. I followed the instructions from the gentoo Linux Nvidia guide, and have run emerge nvidia-glx and emerge nvidia-kernel both finish without error. However, when trying modprobe nvidia it returns (/lib/modules/2.6.16-gentoo-r12/video/nvidia.ko): Unknown symbol in module, or unknown parameter (see dmesg), and the module fails to load. Any help or direction would be greatly appreciated.

What nvidia card do you have? Which driver version are you using?

My bet is that you are trying to use the stable drivers. Unmask the new ones and use those. That should solve your problem unless you have an older card, and then you will need to unmask the legacy drivers and use those.

Thanks for the quick response, I'm very new to Gentoo. The card is an VGA compatible controller: nVidia Corporation NV25 [GeForce4 Ti 4600] (rev a2). Please forgive me for asking, but what commands do I issue to unmask the newer drivers, and how can I tell what version of the driver I'm currently using?

I got the module to load after following http://gentoo-wiki.com/HOWTO_Unmask_Nvidia_Drivers thanks for the tips.
