When fighting to make my Radeon AIW card work, I learned that the issue 
is that the init required to get the AIW series cards ready to 
overlay/capture is nontrivial.   /dev/videoX does become available once 
the card is initialized and xawtv or avview are running. Supposedly this 
is true even if you minimize or move xawtv offscreen.  Admittedly, I 
haven't run a capture test with that scenario, as I gave up on the AIW 
before that point.  If the last bit is true, it would be possible to 
start X, start the backend with a hack to use xawtv-remote to control 
the tuner, and then start the frontend, in that order... I have no idea 
what kind of work would be needed on the backend to make this ugly 
scenario work.  I don't intend to try.  My Radeon AIW is back in my 
winblows machine.
