I experienced the exact same behaviour as Philip Frei. On my system, hal-device-manager was already installed. The installation of acpi-support-base made gnome-power-manager's hibernate feature work.
The suspend function still triggered a "Suspend Problem - Your computer failed to suspend" error message. gnome-power-manager should probably depend on these two packages. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
