Did you rebuild your kernel ? what does dmesg|grep -i ipf say ?

These devfs errors are because you didn't build your kernel with
devfs support enabled.  You can turn off devfs support by commenting
out the -DDEVFS in /usr/src/lkm/if_ipf/Makefile.

While I'm on this subject - by default devfs support is not included with
any modules, due to nothing defining #DEVFS during compilation. Seems
to be something that needs addressing - either devfs should become
non-optional, or stubs should be included.

Cheers,
Julian.
