Either you or I dropped the mailinglist is CC'd. I've added it back. 
Please ensure the mailinglist is CC'd at all times.

Correct.

If it's not found during an i2c scan then it's probably held in reset by 
a GPIO. YOu'd need to figure out which GPIO needs to be raised. I don't 
know the 7130 framework very well by I suspect running regspy.exe (from 
the dscaler project) on a windows system will probably show you the gpio 
configuration that windows uses when the TV playback software is running.

I don't normally force load drivers with card=X. I typically just start 
patching the [7130] tree with the correct PCI'd, attach structs etc. 
It's easier that guessing - which leads to bad assumptions and mistakes.

You can use the other trees [ cx23885, cx88 ] for reference code to show 
how to attach tuners and demods.
