I you are using binary modules supplied by ivtv, then they will work
best with the kernel they were compiled for.  They _might_ work with
later kernels.  The kernel developers really dislike binary modules since
they tend to break things in unpredictable ways - this is even more
of a problem if the kernel release has changed since inter module
dependencies _will_ change.

Have you tried the video4linux module?  If it works with your ivtv stuff
its probably your best bet.
