Check if you have LOOKUP entries for those files in /etc/devfsd.conf

See "man devfsd.conf" for the syntax of "LOOKUP".

That may work if you have this line in /etc/devfsd.conf:

LOOKUP          .*              MODLOAD

Try "modprobe -C /etc/modules.devfs /dev/ppp0" to see if modprobe
understands your /etc/modules.devfs.
