First, an update to 2.6.16 could mean you now have more than 1 copy of
the msp3400 module installed - a new one from the kernel, and one from
ivtv. Make sure you only have the kernel provided one installed, then
run depmod again.

Also, check your modprobe.conf file for the msp3400 alias line - this
should not be needed any more as the kernel-provided version should be
