More info:
In my SVC subclass -viewDidLoad, the parent/child relationships are set up correctly.
By the time -viewWillAppear in my nav controller's root VC is called (the first time the split view is displaying the popover), the SVC-UINavController parent/child relationship has been broken.
I put a UINavController subclass in there to break on -removeFromParentViewController, but it never gets called, even though that navcontroller's parentViewController property is nulled.

As of iOS 5, a presented controller will return nil for the parent (if there is no parent), instead of the presenting controller, as it had before. It may be you're looking for .presentingViewController. Try it.
