I made the adapter and the driver mod. 
It works. And the picture quality is visibly better!   :-)

I found Reichelt Elektronik (http://www.reichelt.de) to be a cheap 
and fast source for quality parts. 
For example, the S-Video cable costs DM 1.80 there and has 
gold-plated plugs. Conrad charges DM 9.95 for a lower quality cable.
Also, my order got here within 2 days. My Conrad orders usually
take at least a week.

I used the following parts:

AK 660     (slot cover, 6-pin Mini-DIN socket, jumper cable, jumper plug) 
AVK 157    (S-Video cable)
EB-DIO M04 (4-pin Mini-DIN socket)

Unfortunately, the 6-pin Mini-DIN (hosiden) socket and the 
4-pin Mini-DIN socket are not compatible, so I had to take
the 6-pin Mini-DIN socket off and attach the 4-pin Mini-DIN 
socket to the slot cover using a home-made metal sheet.
I also had to re-wire the jumper plug, which is easy when
you carefully lift up the tabs on the side of the plug.

Check out http://kabelfaq.de for the hosiden plug pinout.

For the driver mod, I inserted a 
                VidMode(dvb, CVBS_YC_OUT);
at the end of InitFront.
