Hi Patrick,

I'm also affected by this region specific problem (in Melbourne,
Australia) and have been following this thread.  I was about to give
up on the card, and dare I say, admit defeat and sell it off to a
Windows user!  It's good to see that you have a good relationship with
the chip manufacturers and have managed to secure the knowledge to
resolve the problem as they have done so with the windows drivers.

I don't have any driver development experience so I can't assist you
here on the code side but I'd be more than happy to apply any
diffs/patches and test as appropriate.  Also assisting with
documentation might be another way I can reciprocate.  Please let me
know if I can help out in any way.
