The code to make it work already is in the DVB-T tree, somebody "just" needs to glue the TDA10046 frontend to the existing VP7045 backend code, Steward has started this work but I don´t know if he has progressed further than the attached diff.
The firmware needs to be extracted from the windows driver, I have the information needed for that, but hopefully we will be allowed to redistribute the firmware instead.
I think Chris has both the new and the old stick, so he would be a perfect tester.
That is about all I know.
