Given Daisuke's reply in http://www.redhat.com/archives/crash-utility/2012-February/msg00113.html:

  I overlooked lazy allocation case in my explanation... In this sense,
  the warning message might be unkind to users. Still, there's a way of
  checking each page's status by a variety of crash sub-commands.

I was under the impression that Daisuke would prefer to keep the messages
in place in order to give the user notification that those pages are not
accessible.  But I may have misunderstood his intentions.

In any case, since the new version functions correctly, I have posted
the version 1.1 on the extensions page.  

Thanks,
  Dave
