328 Some i386 machines totally fail to operate with some or all of ACPI disabled.
329 Other i386 machines fail with ACPI enabled.
330 Disabling all or part of ACPI on non-i386 platforms (i.e., platforms where
331 ACPI support is mandatory) may result in a non-functional system.

342 ACPI sub-devices and features that can be disabled:
345 Disable all ACPI features and devices.
352 Disabling will avoid scanning the ACPI namespace entirely.

356 ACPI namespace.
360 ACPI namespace will still be scanned.
363 Supports ACPI button devices (typically power and sleep buttons).
372 Supports the ACPI Embedded Controller interface, used to communicate
376 Supports an ISA bus bridge defined in the ACPI namespace,
380 Supports an ACPI laptop lid switch, which typically puts a
