I was wondering myself why the yell was missing: turns out to be a 
driver bug. It will yell if the saa7127 driver was compiled as a kernel 
module and the kernel module was missing, but it would say nothing if 
it wasn't in the kernel at all! This is now fixed and will be in the 
next ivtv release.
