no, 
I'm referring to Serdar Dere and the Medion CTX925_V.1 DVB-T/TV/DVB-S

There are no patches yet, neither for the Medion Quad nor for your card
to get DVB-S working, but the components are likely supported.

In your case there are two saa7134 PCI bridges, which behave like two
seperate PCI cards in the special blue PCI slot.

The 16be:0005 bridge is assumed to handle DVB-S and has a tda10086ht
channel decoder and Andrew recently wrote support for it.

Your DVB-S tuner is labeled as SD1878/SHA. Should be the same like here.

And there were these patches recently to support it.

So this looks not bad, but maybe Hartmut can explain a little, what are
the difficulties with two PCI bridges and two frontends.

Cheers,
Hermann
