Do you have the saa7127.ko kernel module, and is it loaded? There were some 
issues with some Fedora kernels -- and it might've made its way to CentOS 
kernel.

With some kernels, I recall that saa7127.ko module wasn't getting 
automatically loaded, for some reason.  Manually modprobe it before loading 
ivtv-fb.ko.

With other kernels, saa7127.ko wasn't even built, for some reason. In those 
cases, you'd have to grab video4linux, build just the saa7127.ko module, and 
install it.
