This patch enhances the sculpt manager to drive the system state
and manage the lifecycle of driver components during suspend-
resume cycles.
The new Power options can be found in the System menu. The suspend
and power-off controls are presented only when the acpi-support
option is activated.
Note that the USB controller is hard restarted when resuming from
suspend. Hence, all components that depend on USB are restarted
implicitely.
