This may be a solution that is not forward compatible:

If you do not install the signed extensions on a current OS and then your end-user updates the OS, your solution may break.

IIRC, there is a WWDC session covering this. It involves adding related OS requirements to the kexts (using kpi.something versions among other things). And then you can install the 2 flavored of the extensions at the same time.

kexts are usually pretty small, so do the simple thing: make two packages, and have your installer select one package for the different OS on the target volume.

In your dist, this looks a little like this:
