I had the same error about 20 minutes ago :-) I think it is related to frame buffer splash. I use Gentoo 2005.1 and I wanted to use fbsplash. Then I configured my kernel options like this:
Linux Kernel Configuration: 2.6
Device Drivers > Graphics support:[*] Support for frame buffer devices
<*> VESA VGA graphics support
VESA driver type (vesafb-tng) --->
(HRESxVRES@FREQ) VESA default mode # pick resolution@freq of your own here !
# 8pp is the only one supported for this time
# Ex: (1024x768@72)
Device Drivers > Graphics support > Console display driver support:[*] Video mode selection support
<*> Framebuffer Console support
At first I activated the Nvidia Framebuffer Support
in the kernel but nvidia driver gave an error about this. So I deactivated this option and recompiled kernel.
And after compiling the kernel I got the same error:
Error inserting nvidia (/lib/modules/2.6.8-24-default/kernel/drivers/video/nvidia.ko): No such device
And also there is nvidia.ko in this directory.
After deactivating framebuffer option completely in the kernel and compiling I finally managed to work nvidia driver again.My graphics card is GeForce 2MX 400.
And in Gentoo the stable display driver doesn't work as expected.
So I use the unstable ones:
