That’s just how extra modules work: they are not kernel built-in (hence the name extra), and must be build using the kernel headers corresponding to the running kernel. Both nvidia and bbswitch can be compiled for any custom kernel, I suggest that you take a look at DKMS (search for that in the wiki) and corresponding bbswitch-dkms and nvidia-dkms package (not sure about the name, but must be something like this).
