A compatibility table by model and feature is maintained on the web

If you are compiling this driver as included in the Linux kernel
sources, simply enable the CONFIG_ACPI_IBM option (Power Management /
-ACPI / IBM ThinkPad Laptop Extras). The rest of this section describes
-how to install this driver when downloaded from the web site.
-
-First, you need to get a kernel with ACPI support up and running.
-Please refer to http://acpi.sourceforge.net/ for help with this
-step. How successful you will be depends a lot on you ThinkPad model,
-the kernel you are using and any additional patches applied. The
-kernel provided with your distribution may not be good enough. I
-needed to compile a 2.6.7 kernel with the 20040715 ACPI patch to get
-ACPI working reliably on my ThinkPad X40. Old ThinkPad models may not
-be supported at all.
-
-Assuming you have the basic ACPI support working (e.g. you can see the
-/proc/acpi directory), follow the following steps to install this
-driver:
-
- - unpack the archive:
-
- tar xzvf ibm-acpi-x.y.tar.gz; cd ibm-acpi-x.y
-
- - compile the driver:
-
- make
-
- - install the module in your kernel modules directory:
-
- make install
-
- - load the module:
-
- modprobe ibm_acpi
-
-After loading the module, check the "dmesg" output for any error messages.

Features
--------
with this, do send me your results (including some complete dumps with
a description of the conditions when they were taken.)
-EXPERIMENTAL: LCD brightness control -- /proc/acpi/ibm/brightness
------------------------------------------------------------------
-
-This feature is marked EXPERIMENTAL because the implementation
-directly accesses hardware registers and may not work as expected. USE
-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.
+LCD brightness control -- /proc/acpi/ibm/brightness
+---------------------------------------------------
This feature allows software control of the LCD brightness on ThinkPad
models which don't have a hardware brightness slider. The available
The <level> number range is 0 to 7, although not all of them may be
distinct. The current brightness level is shown in the file.
-EXPERIMENTAL: Volume control -- /proc/acpi/ibm/volume
------------------------------------------------------
-
-This feature is marked EXPERIMENTAL because the implementation
-directly accesses hardware registers and may not work as expected. USE
-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.
+Volume control -- /proc/acpi/ibm/volume
+---------------------------------------
This feature allows volume control on ThinkPad models which don't have
a hardware volume knob. The available commands are:
echo 'level <level>' > /proc/acpi/ibm/thermal
+EXPERIMENTAL: WAN -- /proc/acpi/ibm/wan
+---------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature shows the presence and current state of a WAN (Sierra
+Wireless EV-DO) device. If WAN is installed, the following commands can
+be used:
+
+ echo enable > /proc/acpi/ibm/wan
+ echo disable > /proc/acpi/ibm/wan
+
+It was tested on a Lenovo Thinkpad X60. It should probably work on other
+Thinkpad models which come with this module installed.
