There is such a sysgen parameter; you have to put

	options		IPCMESSAGE

into your config file.  The "GENERIC" config file has that, along with

	options		IPCSEMAPHORE
	options		IPCSHMEM

but the other Sun-supplied config files do not.  Make sure the kernel on
all the machines in question was configured with the S5 IPC feature(s)
you want; if not, change the config file and rebuild the kernel.
