You are more or less on the wrong mailing list. The correct list for driver related questions is the drivers mailing list:
<http://lists.apple.com/mailman/listinfo/darwin-drivers>
Andrew Myrick has already given you some good advice to getting started.
I would suggest you consider starting with an existing published driver similar in function to the driver you are wanting to port, and modifying it for your specific hardware.
You may believe that your driver is not calling those power managment routines, but it will in fact call them as part of the IONetworkController::start() function or as a result of your override of this function.
Here's a dated but still useful overview as a starting point:

Here's the Apple reference material:
