I've done it before using a post save signal, although I had lat,lng = NULL in the schema so that differs from your request here. After saving, I would issue an update. I forget why I didn't use a pre-save signal.
Aside from signals, you may also be able to use a model field default with a callable to set the lat/lng of the FarmersMarket object. It's an idea I haven't tested, so I'm not positive it will work. You could write some geocoding middleware that sets request.POST data in some way as it passes through. I don't really like this solution since it is kind of "magical."
