Here is an update on the whole TRIM/SSD swap issue.

The Linux kernel has had "Discard" support for swap since 2.6.29, and basically uses TRIM automatically for all swap functions. If you don't have a device that actually supports the "Discard" commands then apparently there is no problem.

This man page has some of the info:

http://linux.die.net/man/2/swapon

and this page explains it a bit more:

Bottom-line seems to be that Linux supports SSDs for swap use.
