+          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).
