I don't think this is possible with the current XSL-FO spec.
The XSL-FO spec does not provide automatic numbering of footnotes
on a page.  The XSL stylesheet generating the FO output has
to produce the numbers, but it doesn't know where the
page breaks are.  Those are created by the FO processor.
So I think only consecutive numbering of footnotes
within a chapter is possible.

The current version of the DocBook XSL stylesheets (1.60.1)
does put out a footnote-separator line.  Unfortunately,
FOP does not support that XSL-FO instruction.  See:

http://sources.redhat.com/ml/docbook-apps/2002-q4/msg00320.html

The XEP FO processor renders it properly, for example.
