Ok, I see. So there's no "common" method to do this, right? It may
differ from module to module...

Initially I thought that's a really simple task... And now it doesn't
seem to be like that, especially for those who use multiple custom
kernel modules...

Ok, thanks a lot!
I'll try it first, while starting to read about DKMS... Anyway, I'm
curious to do it the right way.
