tracking down suspend/hibernate bugs?

In gutsy I believe the chain is this:

gnome-power-manager -> hal
(/usr/lib/hal/scripts/hal-system-power-suspend) -> acpi-support

most of the actual work occurs in acpi-support.

hal may call a different tool than acpi-support if it is available
though, see /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
for full details.
