nvidia driver installation impossible after upgrading to kernel 3.2.6

[softize]

After the last 2 kernel updates it was easy to install the nvidia driver from the nvidia homepage.
I did:
apt-get install linux-headers-<version>
and then
sh ./NVIDIA.... --kernel-source-path /usr/src/linux-headers-<version>

But this time (with kernel 3.2.6) that simply doesn't work. It tries to install, then a standard (outdated)
general errormessage from nvidia is showing up (saying something like "if you use kernel 2.4 do this, if you use kernel 2.6 do that, blahblah").
I even tried
sh ./NVIDIA.... --add-this-kernel
but it ends up with an error saying the kernel doesn't match. uname -a is really showing 3.2.6 (so does the grub bootmenu) so I have that kernel.
It is simply not compatible with the nvidia driver! (Maybe because it's a "custom" kernel from the backtrack distro?).

How do I get my graphics card (Nvidia GeForce M460 in a Notebook) running in kernel 3.2.6? I use 32 bit, KDE.

Problem solved.
As I learned, I had to to this to prepare the kernel sources:
prepare-kernel-sources
cd /usr/srv/linux
cp -rf include/generated/* include/linux/
After that, installing the NVIDIA..... .run file works fine (even without the need for using the "--kernel-source-path" or the "--add-this-kernel" parameters).
Thanks to the people who told me this solution via private message and bugtracking site. My fault. Didn't know about the prepare-kernel-sources.

NICE!!!

All I had to do was run the first command you suggested:

prepare-kernel-sources

Took me three days to find this solution, thanks again...
