I had the same problem as you, and this is what I did.
Install the nvidia-kernel-source. (aptitude install
nvidia-kernel-source).
The file nvidia-kernel-source.tar.gz is in /usr/src
Unpack it and compile it
cd /usr/src/modules/nvidia-kernel/nv
make
(if you don't have the compiler installed, install build-essentials)
Now, in /lib/linux-restricted-modules/<kernel version>/nvidia is your
old nvidia kernel module (unlinked object files). Delete these, copy all
the .o files from /usr/src/modules/nvidia-kernel/nv to this directory.
In /etc/defaults/linux-restricted-modules-common, disable nvidia_legacy
and nvidia_new
(just add this line)
DISABLED_MODULES="nvidia_legacy nvidia_new"
Now, reboot and you should be using the new nvidia modules
