If I understand you right, you want footnote citations with a special 
handling of repeated citations? In that case I indeed have a workaround. I 
attached it to this mail.

It will print out the first citation full (alternative=data), each further 
citation short (author, year and title) and each direct repetition with 
"Ebenda" (which is the German version of "ibidem", afaics). You can ofcourse 
change these strings, they are defined at the top of the file.

Examples:
  \mycite[some_bib_entry]
  \mycite[prefix={Vgl. }, page=123, chapter={Introduction},
   suffix={some more text.}][some_bib_entry]

I hope that helps.

Best regards,
Andreas.
