There are indeed facilities for ephemeral swap encryption in Linux; I've
actually done it by three different methods to date (you'll have to look
up the exact docs used, though):

* Loop-AES module in Fedora Core 4-6 (AES-256, CBC);

* Dm-crypt in Fedora 7 (AES-256, LRW);

* Persistent (passphrase-based) root filesystem encryption from
install-time, via Dm-crypt (AES-256, CBC:ESSIV-SHA256), and ephemeral
("random-key") swap area encryption via the same method (and identical
module, cipher, and mode-of-op), in Debian 4.0.

The first two were before installers included this kind of stuff
(AFAIK), and so I sort of hacked it together using some scripts I wrote;
in the third, the functionality had been integrated into the installer. =:oD
