Could using a custom error response page help you out? ...see http://code.google.com/appengine/docs/java/config/appconfig.html#Custom_Error_Responses
It could display another site than the default one in case of a DoS error; that HTML page could use a META redirect to redirect the user to some meaningfull location (outside your current GAE or to a second instance of it?!). A whitelist would be of course the real solution...
