The entire element needs to be in the "element_hi_format" format, not just
the pin/pad lines.

Try 

./QueryLibrary.sh . pcblib geda_SO8 SO8 SO8

to see an example.  I did a quick look and it looks like the footprints
which currently use the hi-res format are those which make use of the
COMMON_SMT_DIL_MIL and COMMON_SMT_DIL_MM macros.  This includes things
like SO, SOJ, stuff from ~cts and ~minicircuits, and others.  Also,
all of the QFN sockets in the ~johnstech library.  Looks like the 
non-socket QFN footprints in ~geda have not been updated.  Sorry if I
mistyped on that.
