that is also somewhat distribution dependent, but

install cx88xx /sbin/modprobe --first-time --ignore-install cx88xx && { /sbin/modprobe cx88-dvb || :; }

in /etc/modeprobe.conf should do. Run "depmod -a" after adding it.

The card is auto detected since 2.6.13, previously people even used
card=19 for it, since it is based on that design.

Only support for the analog input was forgotten, but added now.
Else it is known working, likely you need a better antenna.

I can't see anything wrong, maybe somebody else is more aware.
"scan de-Ruhrgebiet" should find everything, if the antenna is good
enough.

You also find a de-Ruhrgebiet "channels.conf" in dvb-apps from mercurial
at http://www.linuxtv.org/repo in util/szap/channels-conf/dvb-t for
"tzap".
