Since I have never had this problem, I don't use the tuner option, but 
this looks correct.
The only other point would be to see that the PVR500 is in a lower 
numbered PCI slot than the PVR150, so it will be seen first by the 
system. I don't know of any other method of determining the loading 
order. It *IS* a computer, and therefore the order is deterministic but 
the method used is kinda obscure for most of us.
At a guess, I would say that the card listed first in lspic will be the 
one the computer ALWAYS finds first (assuming you do not swap slots).

My choice would be to put the PVR500 first, as if you can get it 
working, you have 2 tuners. Then work on the options to add the PVR150. 
So invert the order you give above  tuner=57,57,50

You may have to swap slots to get that to work.

If that does not work, you google 'ivtv tuner option', you will find 
some wiki pages, one of which (about 3rd or 4th listed) discusses the 
ordering for a manual modprobe (about ivtv version 3 or 4 or so)..But 
you may want to try that sort of ordering to ensure that the firmware is 
properly loaded if the 'automagic method (with tuner option) does not work.
