I wonder which would be more useful:  this, or just dumping the full
dump and using crashinfo to create a text summary after reboot.  Of
course, crashinfo could be enhanced to show anything it's currently
missing (relative to the text dump).  This would have the advantage of
doing less stuff at dump time.  Yours would have the advantage that it
exists and works.  :)  Thoughts?

Yes, please.  I've run into this occasionally, but it never annoyed me
enough to fix it.  Procrastination pays off yet again.  ;)
