This driver provides support for extra features of ACPI-compatible ASUS laptops.
It may also support some MEDION, JVC or VICTOR laptops (such as MEDION 9675 or
VICTOR XP7210 for example). It makes all the extra buttons generate standard
ACPI events that go through /proc/acpi/events and input events (like keyboards).

switching the LCD backlight on and off, and most importantly, allows you to
blink those fancy LEDs intended for reporting mail and wireless status.

Compatibility notes:
ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
supported the input layer, and sent events over the procfs ACPI event
interface.
To avoid sending duplicate events over the input layer and the ACPI
event interface, thinkpad-acpi 0.16 implements a module parameter
(hotkey_report_mode), and also a sysfs device attribute with the same
name.
Make no mistake here: userspace is expected to switch to using the input
layer interface of thinkpad-acpi, together with the ACPI netlink event
interface in kernels 2.6.23 and later, or with the ACPI procfs event
interface in kernels 2.6.22 and earlier.
If no hotkey_report_mode module parameter is specified (or it is set to
zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
and earlier, also allows one to change the hotkey_report_mode through
sysfs. In kernels 2.6.23 and later, where the netlink ACPI event
interface is available, hotkey_report_mode cannot be changed through
sysfs (it is read-only).
If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
be changed later through sysfs (any writes will return -EPERM to signal
that hotkey_report_mode was locked. On 2.6.23 and later, where
hotkey_report_mode cannot be changed at all, writes will return -EACCES).
hotkey_report_mode set to 1 makes the driver export through the procfs
ACPI event interface all hot key presses (which are *also* sent to the
input layer). This is a legacy compatibility behaviour, and it is also
the default mode of operation for the driver.
hotkey_report_mode set to 2 makes the driver filter out the hot key
presses from the procfs ACPI event interface, so these events will only
be sent through the input layer. Userspace that has been updated to use
the thinkpad-acpi input layer interface should set hotkey_report_mode to
2.
Hot key press events are never sent to the ACPI netlink event interface.
Really up-to-date userspace under kernel 2.6.23 and later is to use the
netlink interface and the input layer interface, and don't bother at all
with hotkey_report_mode.

A user-space daemon, acpid, typically reads /proc/acpi/event

These events are now delivered to user-space either
via the input layer or as netlink events.
This build option enables the old code for legacy

be moved under CONFIG_ACPI_PROCFS, and then deleted.
