Problem nforce SuSE

[alexmulo]

I have suse 9,1 all modernized and when I try to install driver nforce they give me this error:

ERROR: The kernel header file

'/lib/modules/2.6.5-7.108-default/build/include/linux/kernel.h' does
not exist. The most likely reason for this is that the kernel source
path '/lib/modules/2.6.5-7.108-default/build' is incorrect. Please
make sure you have installed the kernel source files for your kernel;
on Red Hat Linux systems, for example, be sure you have the
'kernel-source' rpm installed. If you know the correct kernel source
files are installed, you may specify the kernel source path with the
'--kernel-source-path' commandline option.
What I must make?
THANKS
