Driver nvidia debian

Bonjour,

J'essai désespérement d'installer le driver nvidia pour ma carte graphique est NVIDIA Corporation NV18 [GeForce4 MX 440 AGP 8x].

J'ai téléchargé le dernier driver sur le site de nvidia, ai quitté X, suis passé root et j'ai lancé le .run

Voici le log d'erreur :

Using: nvidia-installer ncurses user interface
-> License accepted.
-> No precompiled kernel interface was found to match your kernel; would you li
ke the installer to attempt to download a kernel interface for your kernel f
rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: Yes)
-> No matching precompiled kernel interface was found on the NVIDIA ftp site;
this means that the installer will need to compile a kernel interface for
your kernel.
-> Kernel source path: '/usr/src/linux'
-> Performing CC test with CC="cc".
ERROR: If you are using a Linux 2.4 kernel, please make sure
you either have configured kernel sources matching your
kernel or the correct set of kernel headers installed
on your system.

If you are using a Linux 2.6 kernel, please make sure
you have configured kernel sources matching your kernel
installed on your system. If you specified a separate
output directory using either the "KBUILD_OUTPUT" or
the "O" KBUILD parameter, make sure to specify this
directory with the SYSOUT environment variable or with
the appropriate nvidia-installer command line option.

J'ai un noyau 2.6.8-1-k7 et les sources sont dans /usr/src/linux.
Quelqu'un a une idée de ce que je dois faire ??

Merci d'avance.
