YES - that is nearly my setup (iOS 4.3.2). I don't have the
intermediate UINavigationController, but the view has an
UINavigationBar.
Any ideas on how to locate an arbitrary view controller? The following
only locates the 5 associated with the Tab Bar, and not the top most
PasswordPromptController (which was presented modally).
It sure would have been helpful if viewWillDisappear was sent as
documented. When the home button is pressed, and the home screen is
presented, the view has clearly disappeared (no offense Alex).

- (void)applicationWillResignActive:(UIApplication *)application
{
if(tabBarController.viewControllers != nil)
[self clearPasswords:tabBarController.viewControllers];
}
- (void)clearPasswords:(NSArray *)viewsControllers
{
Class passwordPromptClass = [PasswordPromptController class];
for (UIViewController * viewController in viewsControllers)
{
if ([viewController isKindOfClass:passwordPromptClass])
[(PasswordPromptController *)viewController clearPassworAndPin];
}
}
