If your driver is in the kernel, then you dont need that. All processes use system-calls (or ioctls) to send messages and when they do recv(), they get a pointer to a location (where they are mapped to via mmap) and they can read directly. In this scheme, you dont need any traditional UNIX IPC mechanism to work.
Thanks, Rajeev
