-ACPI support
+ACPI Support
 CONFIG_ACPI
-  The Advanced Configuration and Power Interface is a standard
-  designed to allow the operating system more control over power
-  management issues, such as suspending a computer in a low power
-  consumption state after a certain time of inaction. It aims to be
-  an improved version of APM (see below). ACPI has to be
-  supported by the motherboard. You can read more about the standard
-  at http://www.teleport.com/~acpi/ . 
-
-  If your computer supports ACPI and you want to use it, say Y here.
-  You will then need supporting software; for location and more
-  information, please read Documentation/pm.txt and the Battery
-  Powered Linux mini-HOWTO, available from
-  http://www.linuxdoc.org/docs.html#howto .
-
-  If you say Y here and also to "Advanced Power Management" (APM)
-  below, then ACPI has precedence in the sense that, if your hardware
-  supports ACPI, it will be used and APM won't.

-ACPI interpreter (EXPERIMENTAL)
-CONFIG_ACPI_INTERPRETER
-  If you say Y here, an ACPI interpreter will be included in your
-  kernel, eventually making the full range of ACPI features
-  available on systems that support ACPI.  Note, this option will
-  enlarge your kernel by about 120K.

-  The interpreter is currently experimental so only say Y if
-  you know what you are doing.

-Enter S1 for sleep (EXPERIMENTAL)
-CONFIG_ACPI_S1_SLEEP
-  If you say Y here, ACPI compliant devices can enter level 1 of ACPI
-  saving power levels. Basically, this will let them enter sleep mode.
+  ACPI/OSPM support for Linux is currently under development. As such, 
+  this support is preliminary and EXPERIMENTAL. Configuring ACPI support
+  enables kernel interfaces that allow higher level software (OSPM) to
+  manipulate ACPI defined hardware and software interfaces, including
+  the evaluation of ACPI control methods. If unsure, choose N here.
+  Note, this option will enlarge your kernel by about 120K.
+
+  This support requires an ACPI compliant platform (hardware/firmware).
+  If both ACPI and Advanced Power Management (APM) support are
+  configured, ACPI is used.
+
+  This code DOES NOT currently provide a complete OSPM implementation --
+  it has not yet reached APM's level of functionality. When fully
+  implemented, Linux ACPI/OSPM will provide a more robust functional
+  replacement for legacy configuration and power management interfaces,
+  including the Plug-and-Play BIOS specification (PNP BIOS), the Multi-
+  Processor Specification (MPS), and the Advanced Power Management 
+  specification (APM).
+
+  Linux support for ACPI/OSPM is based on Intel Corporation's ACPI
+  Component Architecture (ACPI CA). The latest ACPI CA source code,
+  documentation, debug builds, and implementation status information
+  can be downloaded from:
+  http://developer.intel.com/technology/iapc/acpi/downloads.htm
