SunOS needs to have System V shared memory (and message queues and
semaphores) installed into the kernal. It is part of the options section
of the kernal configuration file.

options     IPCSHMEM        # Shared memory
options     IPCMESSAGE      # Message queues
options     IPCSEMAPHORE    # Semaphores

These will include the necessary drivers in the kernal.  Hope this is of
some help
