Tim Maroney sent me mail and tech note 80 agrees (as I suspect does
the Standard File chapter of IM-IV--but I don't have it in front me
right now): the dirID is in the low memory global CurDirStore and
the negative of the volume reference number is stored in SFSaveDisk.

My fear that I was either asking a question that had just been
discussed or one that has an obvious answer if I only looked in the
right place, was doubly borne out.  Sorry to add to the noise (red
face), will look much more carefully next time. 

Thanks.
