The link inside /lib/modules/2.6.12-gentoo-r4/ and /usr/src/linux both point the correct kernel-source? Have you changed .config since you compiled and booted your kernel? Try to make bzImage and boot that kernel. Preempt symbols are atleast optional and comes from macros that depens on kernel-config.
No, compiled kernel, booted, installed nvidia-kernel, modprobed. I will try once again next weekend to recompile kernel, and then install nvidia-kernel again, but I am sure that I didn't change .config inbetween. Also, I only have one kernel source installed, and /usr/src/linux is pointing to that source. I have an inkling it may be due to kernel config options, but know so little about them I can't really speculate.

Try to change the kernel pre-emptation. Can be that the nvidia source depends on it beeing enabled for instance.
I upgraded to kernel 2.6.12-r6, and the problem did not occur. Had pre-empting on before, and again this time. I can upload both .config files if you like, to see if the problem is within those options. Now, however, nvidia loads fine. Rhys
