-CONFIG_ACPI_BOOT
-  This option enables the use of ACPI tables for obtaining various
-  boot-time configuration information such as system processors, 
-  memory, and interrupt routing.  
-  
-  ACPI tables supercede legacy BIOS interfaces.  For example, the 
-  Multiple APIC Description Table (MADT) defined by the ACPI 
-  Specification is a replacement for the MP Configuration Table 
-  defined by the MultiProcessor Specification (MPS).
-  
-  You can disable this feature on IA32 systems by adding "acpi_boot=off" 
-  to your kernel command line. (Try "man bootparam" or see the

-
-  IA64 systems do not support legacy BIOS interfaces and thus rely
-  on ACPI tables to boot the system.  No kernel command line options
-  are supported.

-CONFIG_ACPI_INTERPRETER
-  The ACPI Interpreter (a.k.a. ACPI Core Subsystem) provides the 
-  fundamental services required to parse the ACPI namespace, evaluate
-  control methods, and manage ACPI hardware and events.  This 
-  subsystem exposes kernel interfaces allowing higher level software

+CONFIG_ACPI_HT_ONLY
+  This option enables limited ACPI support -- just enough to

+  Table (MADT).  Note that ACPI supports both logical (e.g. Hyper-
+  Threading) and physical processors, where the MultiProcessor 
+  Specification (MPS) table only supports physical processors.
 
-  Note that this option will enlarge your kernel by about 100K.
+  Full ACPI support (CONFIG_ACPI) is preferred.  Use this option 
+  only if you wish to limit ACPI's role to processor enumeration.
 
-CONFIG_ACPI_BUS
-  The ACPI Bus driver enumerates and manages devices in the ACPI 
-  namespace in a manner similar to other bus drivers (e.g. PCI).
-  All ACPI device drivers rely on its services. 
+  There is no command-line option to disable this, but the kernel
+  will fall back to the MPS table if the MADT is not present.
