I am quite happy with s2ram now on my AMD-based vaio, but it started to work with 2.6.17 kernels (Ubuntu Edgy, really), and the three years before that suspend-to-disk (sometime Pavel's, sometime Nigel's) saved the day (yes, it's quite faster to use suspend-to-disk that doing shutdown, reboot, and re-open all the applications). So, please do not dismiss suspend-to-disk as "crap". It has its place under the sun.
