nvidia drivers on Debian Squeeze with kernel 2.6.38 from backports

Q&D way to install proprietary nvidia drivers with dkms on 2.6.38 kernel from squeeze-backports.

1. Install linux-kbuild from Debian Wheezy
2. Install linux-headers from squeeze-backports (with dkms compilation error)
3. Make symlink to generated header:

   
   cd /usr/src/linux-headers-2.6.38-bpo.2-your-version/include/linux
   ln -s ../generated/autoconf.h ./
   

4. Patch nvidia source at /usr/src/nvidia-195.36.31:

5. Reinstall linux-headers to recompile modules
