Eric-
What rpms have you installed I don't think you have the correct firmware 
installed.

on my Fedora 5/6 system I ran this to install my PVR-350 ivtv software.

yum -y install ivtv-firmware
yum -y install ivtv-kmdl-`uname -r`.`uname -m`
yum -y install ivtvdev

your /etc/modprobe.conf looks fine to me (its the same as my working one 
is)  but for the PVR-350 Output to work you do need to add this to the 
modprobe.conf file also.

alias char-major-81 videodev


did you add “vga=791” to the end of all the vmlinuz lines in /etc/grub.conf?

hope this helps

-Matt
