The above two lines are all that is needed in your /etc/modprobe.conf

The ivtv driver can now automatically set a lot of reasonable defaults.  
Try removing these two lines and see if it still works.  Of course you 
may want to leav the options ivtv ivtv_debug=1.  You can modinfo ivtv 
for the autodetect and default settings.

Remove this line.  Modprobe doesn't support the add option anymore.

Add below is no longer supported

This happens with the Redhat (well Fedora) kernel.  A plain kernel from 
kernel.org doesn't have this issue.  Please take a look at this message 
from the ivtv list:


Basically, sys_open et al are no longer to be used in kernel modules so 
Fedora disabled them to get people to update their drivers (much like 
they did with 4K stacks).  Not that I have a problem with this, it just 
forces people that are on the bleeding edge to make sure they don't keep 
old cruft around and gives other distributions time before introducing 
things that may break in the mainstream.
