Thanks for both useful answers.

Stephane, you're right, my users won't like it if the Mavericks compatible driver the installed on ML doesn't work once they update!

Best regards

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:
