Yes, I know insmod and herein the problem lies. I have a module where I want to use functions provided by another module, _if_ it is present, otherwise use modules internal functions.
So if I hardcode the function calls statically in my module, the insmod goes trough of course, if the service module is present. But, it fails if it's not.
So, I want to load up, check if the service module is present, and use it's servides.

I meant that in previous kernel version, some module symbol searching functions were available.
