The patch looks good, with the exception of requesting the cx25840.

I've always been able to run DVB without that driver being present, so 
something is odd with the Leadtek card. I'm not aware of any 
relationship between the cx25840 driver and the DVB core.

You're going to need to find the magic register write that the cx25840 
is performing so we can discuss here. I'd rather we figured that out 
cleanly, than just merged the patch and have the problem linger on.

Other than that, good patch.
