Huh. Well, looking in /var/log/dmesg worked for me, but I'm told this
works in some cases where that doesn't:
# dmesg |grep ivtv
It is best to do this just after booting up also (or after unloading
and reloading the ivtv drivers), otherwise the log may roll over on
you. Looking today at my system that has been up for quite some time, I
get no results.
