This is possible at the moment, but a bit difficult. The Warty kernels
don't include suspend to disk support. If you're happy to rebuild
kernels, you can switch on "software suspend" in the kernel
configuration and try that. gdm can be configured to offer a suspend
option in the system menu, and you can then use that to trigger a
suspend to disk.

We'll be looking into this more closely for Hoary (the next release),
and with a bit of luck we'll have solid suspend to RAM support as well.
