The Red Hat fontconfig package actually has the attached patch in
it. (I haven't submitted for obvious total-hack reasons). A way to do
this as a config option would be nice.
While this patch is more like 1), I do actually know the full pathnames
to these fonts, so 2) would work as well, if it is perhaps a little
less robust. (They are from the ghostscript distribution and don't
render properly with FreeType.)
