Ok, wile waiting for the fix show up in the public mercurial tree I've 
workarounded the issue with a wrapper script which redirects xc_save 
stderr to a file.  There I get this:
   FNI 21 : [10000003,768] pte=25fae063, mfn=00025fae, pfn=00001b00 
[mfn]=deadbeef
   FNI 21 : [10000003,769] pte=25faf063, mfn=00025faf, pfn=00001b01 
[mfn]=deadbeef
   FNI 21 : [10000003,770] pte=25fb0063, mfn=00025fb0, pfn=00001b02 
[mfn]=deadbeef
   [ ... many more of these ... ]

In the source code there where message is printed I find a comment 
saying "/* I don't think this should ever happen */".  Hmm.  It does. 
And probably it is a problem.  "xm save" works now, but I can't restore 
the domain:
  master-xen root /tmp# xm restore /vm/ttylinux/suspend.img
  Error: Could not read store/console MFN

Ideas anyone?  This is a ttylinux instance running out of a ramdisk.
