I do have the latest ivtv installed so I think I am good there.

I do know that the tuners are different.

As one would expect thee the tuner model is the same for both the 500  

Yes the order in modconf is more for convenience of discussion - the  
cards are found in different orders depending on pci slot etc. and I  
don't really have any real expectations of order at this point.

I think have come across the 'option' element in google searches - I  
will see if I can find an example that works. I assume it will follow  
the same pattern as for when used with multiple cards of differing  
types? (I think that is the scenario the examples I have seen follow.)

Adding something like the following at the end of the modprobe.conf  
should work?:
# force tuner options for tuner cards
option tuner = 1,50,57

Thanks for the input!
