Just a follow up to this. It looks like adding "early writeout = y" to my /etc/suspend.conf has worked around the problem. If I had "shutdown method = reboot", then it would resume every time, but with "shutdown method = platform" it would fail to resume most of the time. I'm running a Core 2 Duo with an Intel X18-M 160GB SSD on an intel AHCI controller. Adding "early writeout = y" does not appear to change the progress statistics, or apparent speed of the suspend, but it has now survived 7 suspend/power off/resume cycles that it would never had survived before.
