What is the actual problem? Does the display simply stay black, but the machine is otherwise accessible (e.g. via ssh) or does the machine lock up completely? If acpi-support is working for you, could you please post a list loaded modules right before the suspend (or better, the diff between pm-utils and acpi-support). Does your computer require any quirks (lshal | grep quirk)? Can you experiment with a different set of quirks [1]?
