You have to create an entry in /etc/fstab for swap if you don't use a .swap file on the internal card. (Note that if you do, you can resize it much larger just by using dd to create a big file and mkswap .swap).

For /etc/fstab, I have the line:

/dev/mmcblk0p3 none swap swap priority=-1 0 0

and it "just works".

And a thankyou to Fanoush for adding the date/changelog entry to the webpage.
