The Module API may be the same between versions, but the ABI (B for Binary) is 
not; in fact, it is intentionally not possible to do what you are asking.

NVIDIA, for example, has a "wrapper" around their binary module that must be 
compiled for a given kernel - all it does, essentially, is map the ABI to 
something static for the nvidia.ko, to work around this problem.
