Yes, that is another way to go.  However, in the case where only one 
swap space is configured, I don't believe the kernel will allow it to be 
deactivated (I may be mis-remembering, or perhaps its the case in a UNIX 
SVR4 system?).

So, it may be safer to boot from a rescue CD and work from that 
environment, than to try to use swapoff on a single swap space used by 
the currently running kernel.  And, if you're going to edit fstab and 
reboot anyway, why not just do it from the CD and avoid the fstab edit 
step altogether?

FYI, you should reply to the full list, not to a poster only, as others 
may be interested in the question and answer.

So, I'm sending this to the list, with a CC to you as a courtesy.
