As an ugly workaround, you may create an directory on ufs filesystem, populate it with needed symlinks, and then make a symlink /dev/subdirX -> the directory. I would prefer not to allow users to create the directories on the devfs. On the other hand, I like Solaris approach with devfs on /devices and /dev being populated with short symlinks to ../devices.
