HI Gonzalo,
As Knut said, FreeSurfer is not compiled to run with CUDA 4. If you run ldd command to some freesurfer binary file you notice that the binary file links to libcudart.so.3 library.
You should recompile the FreeSurfer source code. This is what I'm trying to do right now but is not easy and I haven't success yet...
If someone has done it, please explain how...

Hi
You should use Cuda 3.1 which is included with Freesurfer. Freesurfer is not compiled to use Cuda 4.0 or Cuda 4.1

I'm afraid I don't know what's going on there. I've never tried CUDA 4.0.
