FreeBSD 5+ has /etc/devfs.conf and /etc/devfs.rules which include
information regarding permissions and ownership for device nodes
under /dev. These files can even be used for creating fancy names for
devices using symlinks (like /dev/burner for CD-RW devices,
or /dev/floppy and so on). At boot time, /etc/devfs.conf is read,
and /etc/devfs.rules is read whenever new devices are attached to the
system (I believe that's how it works, anyway). Is that what you're
looking for?
