Or just close a memory hogging app or three to free enough RAM that swap is
unnecessary. Just Firefox is probably enough, and certainly OO.org should be
more than enough unless you've got a big leaker open.

Gross overkill.

Comment the swap partition line in /etc/fstab, reboot, mkswap -L, uncomment,
swapon -a. Live CDs will typically find and use whatever swap partitions they
find.

I've done this after the fact swap lable setting lots of times, and doubt it
ever took me more than 30 seconds after figuring out the first time.
