Hi,
I did a quick patch to the code in 3.0-current to allow:
- OVERRIDE_TUNER: allows you to manually choose the tuner type for those
cards that fail to probe properly. See source for legal
values.
- OVERRIDE_DBX: allows you to manually choose DBX or NO DBX for those
cards that fail to probe properly.
0 == no DBX circuit present, 1 == DBX circuit present.
here's a patch against it:

Let me know if it fails to work properly.
