Aha, so it works!!
Case closed :-)

Aha, I don't think you mentioned CUDA before. Or maybe I was not paying 
attention. I have only dealt with CUDA in a non-rt kernel environment... 
presumably you would need to apply the same patch that is used to be 
able to build the glue layer that let's you run the nvidia binary blob 
display driver. I'm attaching the patch I'm currently using to this email.

It's been a while since I installed CUDA so I don't remember much.

I presume you will need to unpack the distribution, find the place where 
the files to be patched are in the tree, patch them and then try to 
install. Sorry, I don't have the time to go through the logs you sent, 
maybe somebody else in the list has the time...

Best luck!
