I'm not sure that's the problem.

I think you might find that the kernel and modules that ship with RH9
were not compiled with the .config that you used.  If you recompile a
kernel or any modules with the .config that came with RH9 you may need
to reinstall all the modules as well as the kernel.

You can always just compile everything with CONFIG_MOD_VERSIONS not
set in the .config but that's asking for trouble later on if you have
more than one build on your system.
