What are the `non-free CID font support data'? Adobe's CMap files?

In this particular case, the used CMap is trivial (the identity
mapping); no external CMap file is necessary to create such a PDF.

It's xdvipdfmx which automatically generates CID-keyed subfonts.

Uuh, don't say `CID-dependent'. This term doesn't exist.

Some terminology: Type1C is a Type 1 font in CFF format (this is much
more compact than the PFA or PFB representation). CID-keyed fonts
depend on external CID CMaps for creation or reading of PDFs.
However, the PDF files themselves *don't* contain CMap files at all,
thus such PDF files can't cause problems with the DFSG.
