-         This option adds support for ACPI suspend states.

-         With this option, you will be able to put the system "to sleep". 
-         Sleep states are low power states for the system and devices. All
-         of the system operating state is saved to either memory or disk
-         (depending on the state), to allow the system to resume operation
-         quickly at your request.
-
-         Although this option sounds really nifty, barely any of the device
-         drivers have been converted to the new driver model and hence few
-         have proper power management support. 
-
-         This option is not recommended for anyone except those doing driver
-         power management development.

-         The Procfs interface for ACPI is made optional for backward compatibility.
-         As the same functions are duplicated in the sysfs interface
-         and this proc interface will be removed some time later,
-         it's marked as deprecated.
-         ( /proc/acpi/debug_layer && debug_level are deprecated by
-           /sys/module/acpi/parameters/debug_layer && debug_level.
-           /proc/acpi/info is deprecated by
-           /sys/module/acpi/parameters/acpica_version )
+         A user-space daemon, acpi, typically read /proc/acpi/event
+         and handled all ACPI sub-system generated events.
+
+         These events are now delivered to user-space via
+         either the input layer, or as netlink events.
+
+         This build option enables the old code for legacy
+         user-space implementation.  After some time, this will
+         be moved under CONFIG_ACPI_PROCFS, and then deleted.
+
+         Say Y here to retain the old behaviour.  Say N if your
+         user-space is newer than kernel 2.6.23 (September 2007).
