That probably means that a required kernel module
is not loaded.

There is no such device in FreeBSD-6. Hint use /dev/cuad,
not /dev/cuaa.

nik:0:~$ ls /dev/cuad0*
/dev/cuad0      /dev/cuad0.init /dev/cuad0.lock

That's only your kernel loaded, no modules.
Either you have the required netgraph nodes
built in your kernel or not at all. You can
see what's builtin in your kernel using:
kldstat -v | grep ng_

Most probably something is wrong with your
kernel and/or your update.

Also, did you rebuild mpd4?
