Eelco Dolstra c83a185090 * Run the ACPI daemon. This allows the system to respond to ACPI
events, like pressing the power button.  The NVIDIA X11 driver also
  needs it to respond to the internal/external monitor switch button
  on laptops.  The power actions should of course be made
  configurable.
