On monday I will have access to the machine and I will look at the card.

I did try this but as of patchset 1029 (a big one) the patching did no longer
work (it might be an error on my part since it is the first time I work
with CVS). But I can say it did not work with patchset 1352, 1334, 1333,
1236, 1233 and 1224.

Meanwhile someone else suggested to me to try the driver from the Metzler
brothers. When loading them I get more information on the output:

   i2c-core.o: i2c core module
   i2c-core.o: driver stv0299 DVB demodulator registered.
   i2c-core.o: driver ves1893 DVB demodulator registered.

I now remember that I did try this driver earlier and later switched
to linuxtv-dvb-1.0.0-pre3, since trying to use dvbtune did not work. I
do remember dvbtune did talk once with the card but then too it
would always return the error 'No such device' when trying to open
/dev/dvb/adapter0/frontend0. Looking back in /var/log/messages I see
that the frontend did load once but after a reboot never again:

Maybe my card is broken or it is a newer card with some other chips on it
so it does not get detected reliable.
