You register the newsfeed with the *global* components registry, not with the 
local root components registry. This is the reason, you will not see it as 
registered. Further, once you restart Zope, the regstration will be gone.

What you need:

root = getRootFolder()
sm = root.getSiteManager()
sm.registerUtility(self, INewsfeed, self.__name__)
