It *sounds* like the card needs some time to stabilize.

You could try using a script (called from /etc/rc.local ) which will 
remmod the  ivtv driver, and then insmod it back. That should trigger 
the udev subsystem.
(Althernatively, there is a script which re-triggers udev, which should 
then recognize the cards.

Have you tested putting these 2 cards into different slots? Or just in 
the other slot?
Have you tested with just one of them installed? And then the other?
In both slots?


There could be some sort of interrupt contention going on which a 
slot-swop would fix, obviating any software work-arounds.
