Re: NVIDIA 5336 issues with RH9 kernel 2.6
You should have the running kernel's source in a directory with the name /usr/src/linux-2.6.4. You should place a link in /lib/modules/2.6.4/ to that source directory, name it 'build'.
ln -s /usr/src/linux-2.6.4 /lib/modules/2.6.4/build
If those two things are already in place and you still can't get it to find the source, then maybe you should instead try using kernel 2.6.x RPMs. It has been awhile since I built 2.6 on RH9 and have forgotten any 'gotchas' I had to deal with.
