Really?!?  I'm using the nvidia module here and it loads just fine - in 
the exact kernel I used to force the error messages above.  I just make 
sure that I compile the nvidia module in the proper environment.

I think I'm going to build a new kernel with CONFIG_MODVERSIONS set, just 
to see what happens.

I scanned your build log and I agree it certainly looks correct.  Yet I do 
the same thing here without a problem.

The most glaring difference I see right now is the use of 
CONFIG_MODVERSIONS.  You use it and I don't.  I'll build a new kernel here 
with that set and see if I can still load everything correctly.
