If you do a websearch you'll be directed to a site out of Holland that goes into the subject in great detail. I just checked my downloaded copy, and only the authors' e-mail is listed.
Mouser Electronics has the required diode at retail.

Somebody on the camera fix mailing list posted a circuit that uses some transistors and resistors to regulate voltage more accurately across changing loads, which is a weakness for the 'diode in series' solution (where the voltage-drop changes with increases or decreases in current flow). Here is the URL:

Check out this, and if you figure out a way to build them reasonably small you could insert it somewhere inside the old camera, in some cases there is room... I think something like this could be built into an aspirin size circuit if you had the technology...
