Absolutno vqrno ! Gledajki v sources na Nvidia se pravi to4no tova, naprimer 
os-interface.c (nv.c analogi4no):

#ifdef CONFIG_MODVERSIONS
#define MODVERSIONS
#include <linux/modversions.h>
#endif

!!! T.e. pravi se proverka !!! 

#define __NO_VERSION__          // tell module.h to not define 
__module_kernel_version
                                // it was already defined for nv.c

#include <linux/module.h>
(indirektno vklu4va modversions.h) ala bla portokala i t.n. 

T.e. v sources na Nvidia vsi4ko si e nared, drug e vyprosa za tova ugly file 
Module-nvkernel deto go razprostranqvat binary-only (mislq 4e skoro ste dadat 
i source-to) ... Ako ima tuka problemi ili bad code togava sao te mogat da gi 
reshat .....

a /usr/src/linux/include/linux/modversions.h koito ot svoq strana include-va 
include/linux/modsetver.h e neobhodim zaradi symbol versioning definitions... 
t.e da se get-net ot kernel sources v module build-a...  t.e. da ima version 
kontrol mezhdu kernel image-to deto e compiled s CONFIG_MODVERSIONS=y i 
module-to bilo to i ugly polu-binary s vyrtelezhki kato os interfaces.....
