Should be. You can see the ivtv0 output contains details on the
decoder, which only the -350 card has. This should then be the first
ivtv card udev handles, so should create the /dev/video0 device.
However, I'm sure there could be timing/hardware issues which will
contradict this.

(It's likely one of the composite inputs, but stranger things have happened...)

When configuring ivtv cards, I've found that there is no golden rule
as to which driver input is the correct one for the particular card. I
use ivtvctl (the -p option changes inputs, the -n lists available
inputs) to change to each input in turn, and then read the device from
mplayer/xine to test whether I'm receiving the feed correctly. Then I
use mythtv-setup to assign the video source (the channel lineup) to
the correct input on the card.
