I'm also interested in this functionality so for now I'm trying to reach it through Inkscape cli verbs functionality, so I began with:
inkscape -g -f input.svg --verb=DialogDocumentProperties
Then I realized that this one does the trick quite well:
inkscape -g -f `pwd`/psone_grafitti-F.Cu.svg --verb=FitCanvasToDrawing --verb=FileSave --verb=FileClose --verb=FileQuit
Hope that helps until --export-area-drawing supports SVG's ;)
