I want to say thanks to the people who responded, including:
	danl@midget.towson.edu
	ee.udel.edu!law
	diku.dk!seindal
	cs.strath.ac.uk!jim
	ariel.unm.edu!rhare>

All agreed that swap space is defined a kernel compile time, via the 
'config' line in /usr/sys/config/machine_name:

	config	vmunix	root on hp0a  swap on hp0b  dumps on hp0b  

The call to 'swapon -a' in /etc/rc allows additional swap space(s) to be
used, provided they are also specified at compile time:

	config	vmunix	root on hp0a  swap on hp0b and hp1b  dumps on hp0b  

The optional swap spaces must also be listed in /etc/fstab.

Now, all I have to do is to get my vendor to pay attention; he does all
the kernel generation.  (For the time being...)

Thanks again.
