The first problem is that most documentation tells you use the 'tuner=2'
or equivalent option with the tuner module.  This will work in most
cases, but with newer versions of the driver is not what you want for
multiple cards.  Instead, use that option with the driver for the card
(e.g., bttv or ivtv).

This lets you use different tuner types with different cards, provided
they use different drivers.

If both cards use the same driver, I don't know if they can use
different tuner types.

Ideally, there should be an API to set the tuner type at run time.  Then
MythTV should proved a config option for each card to specify it. 
Wouldn't it be nice...
