The trick is that the /etc/fstab entry must have all fields filled in,
even if they are meaningless.  So a typical fstab entry is

	/dev/sd1b swap swap 0 0 0

Then the normal swapon -a in /etc/rc will work, assuming you config'd your
kernel for it.  And remember, no blank lines in fstab.

BTW, I noticed a very large improvement in the total disk throughput on a
SCSI based system using 2 swap partitions.  iostat said I was swapping on
a 3/60 at a max of 440 k/s, instead of about 250 for a single disk.  If
you have any Lisp users on your system, you should consider it anyway.  Or
Gnu Emacs (Eight Megabytes And Constantly Swapping :-).
