I just took a mirror and looked on the back of the system I'm using
now...  It has S-Video out - straight 4-pin, not the fancy connector
with the multi-way breakout that my 8400GS has.  Seeing the connector on
the back, I went to my bench in the basement, and was actually able to
find the manual - from several years ago.

It's a Chaintech 6200, with VGA, DVI, and S-Video outputs.  I guess when
I get some spare time, I'll have to try swapping things around.  Will I
need to back-level the driver, in order to make the Overscan option work
again, or to get the overscan slider back into nvidia-settings?
