[linux-dvb] How to change linux kernel module frontend?

Card: Azurewave / Twinhan DVB-C AD-CP300 (Mantis 2033) CI PCI
Driver from: http://jusst.de/hg/mantis/

Compiles and installs, after reboot, it can be found as (dmesg extract)

Most propably problem is exactly same than in here
http://www.spinics.net/lists/linux-dvb/msg24184.html

mantis loads wrong frontend (tda10021 instead of tda10023)

> The chip ID is 0x7d. Probably, your card uses a CU1216-3 with a TDA10023. There are 
> differences between the TDA10021 and the TDA10023.

 > Changed the tuner to TDA10023 and it worked like a charm!

main question is:
How to do that change?
