Thanks a lot! Yes, that gives me the overview I needed.

I grabbed your information and generated a manual page from it where I
also want to describe the other dump formats (when I have some time
left):

   http://www.suse.de/~bwalle/kdump/

That's basically part of the SUSE kdump configuration, maintained in
http://freehg.org/u/bwalle/kdump/.

I just used asciidoc because I hate nroff. I hope it's ok for you to
distribute that manual page.

However, if you wonder, I didn't need that information for documentation
but for page size on PPC64 ... thanks again!
