First thing to do is check your syslog for the ivtv output when the
ivtv modules are loaded to make sure there are no obvious issues with
card detection (could be PVR-350 tuner). The new 2.6.16 kernel (I
think) no longer wants the ivtv-msp3400 alias in your modprobe.conf as
the module is now in the kernel, so this could be one possible cause.

Something like:

tac /var/log/messages |
sed -n '/=\ \ END INIT IVTV\ \ =/,/= START INIT IVTV =/p;
/= START INIT IVTV =/q' |
tac

should print out the relevant ivtv module information.
