I built a new system using kernel 2.6.9-gentoo-r1. after emerging
nvidia-kernel and nvidia-glx I did a modprobe nvidia and recieved the
following error: FATAL: Error inserting nvidia
(/lib/modules/2.6.9-gentoo-r1/video/nvidia.ko): Unknown symbol in module,
or unknown parameter (see dmesg). Iv'e done this on several previous
kernels with no problem. Is there a bug in this kernel?

See dmesg, tell us the unknown symbol or parameter.

Probably, but this is not a bug. Always start by assuming you're the
one with the problem, not the kernel. Besides being modest, it's
usually also easier to fix your own error than someone else's.

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?

dmesg is: nvidia: module license 'NVIDIA' taints kernel.
nvidia: Unknown symbol __VMALLOC_RESERVE

For x86 systems, add the following in arch/i386/mm/init.c in line 44:

EXPORT_SYMBOL(__VMALLOC_RESERVE);

Then recompile the kernel. Fixed the problem for me. It would probably be
better to patch the nvidia kernel glue code instead, but I can't do that.

I have no line remotely resembling that, but nvidia works just fine
here. These are my kernel and driver versions:

sys-kernel/development-sources-2.6.9
media-video/nvidia-kernel-1.0.6111-r2
media-video/nvidia-glx-1.0.6111

Either use a newer driver or drop the Gentoo kernel. Having to manually
patch your kernel should never be required ...

I went back to kernel-2.6.8 and got it working. I'll try 2.6.9 with the
newer nvidia drivers (was using 1.0.5331).
