[linux-dvb] Mantis 2033: tuning still fails

Hello all,
Slowly my Twinhan card is coming to life. Sadly though, tuning fails on all
frequencies. I saw a post on this subject from a few weeks ago. Changing
the tuner from tda10021 to tda10023 helped a lot in that case, but I have
absolutely no idea how to do this. I looked over a lot of source code to
see if I could find where the tuner chip gets determined, but to no avail.
My C skills aren't good enough I fear.. The output of dmesg shows this:

ACPI: PCI interrupt for device 0000:01:09.0 disabled

Any help would be greatly appreciated!
