RH use module-info to map devices to kernel.  kernel.h just says how
the installed kernel was compiled, almost irrelevant if you build your
own.  I doubt that either are causing your problem.

Binary only modules (BOM) either have no source or the source is not
GPL.  Linus has "allowed" binary only kernel code as modules.  Binary
only code cannot be linked into the kernel if you distribute the
kernel.  What you do in the privacy of your own machine is up to you,
the GPL only bites if you distribute your kernel.

If your kernel requires a binary only driver in order to boot then that
driver must be a module.  To load a driver at boot time, you have to
use initrd.  My attitude is that unless you absolutely need initrd,
don't use it.

IANAL, not speaking for anyone except myself, blah, blah, blah.
