-          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 )
+          For backwards compatibility, this option allows
+          depricated /proc/acpi/ files to exist, even when
+          they have been replaced by functions in /sys.
+          The deprecated files (and their replacements) include:
+
+          /proc/acpi/info (/sys/modules/acpi/parameters/acpica_version)
+          /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)
+          /proc/acpi/fadt (/sys/firmware/acpi/tables/FACP)
+          /proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer)
+          /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
+
+          This option has no effect on /proc/acpi/ files
+          and functions which do not yet exist in /sys.
+
+          Say N to delete /proc/acpi/ files that have moved to /sys/
