They should appear automatically.  You should have one if you have bpf
configured or the kld loaded.  When you open them, they clone.  For
example,

  $ ls -l /dev
  ...
  crw-rw-rw-  1 root  wheel      30, 0x00030004 Apr  7 14:52 audio0.3
  crw-------  1 root  wheel      23,   0 Apr  7 14:52 bpf0
  crw-rw-rw-  1 root  wheel      21,   0 Apr  7 14:52 bpsm0
  $ tcpdump
  tcpdump: listening on wi0

MAKEDEV no longer exists in FreeBSD 5.0.  devfs creates the device
nodes automatically.
