I think that it's possible, adding one wire :-) ; read below.

I developed the "budget patch" idea/hardware and the first DVB_driver patch
for it; on the documentation that was available for download at Wiki page
(sorry, again the link is broken :-( ), I commented that this "budget patch"
should be much more easy to do on TT_DVB-S rev 2.2 that on previous versions
(1.3, 1.5, 1.6 & 2.1), being enought to interconect two pins of the SAA7146;
I don't had/have this rev 2.2 card, but from reports and pictures, also for
rev 2.3 cards, I think that it should be easy :-).
On a alternate way, instead of link the two SAA7146 pins (to regenerate a
pseudo VSYNC signal), one could mount the two CMOS divider circuits (sorry,
I don't remember now the references, but are on the refered documentation)
on the pads that are reserved for its, on rev 2.2 & 2.3 PCB; to more details,
on rev 2.3 cards this pads are below the PCB string 'DVB-s Rev.: 2.3'.
I don't have the rev 2.3 card, so I can't verify the feasibility of my idea.
