This driver used to be named ibm-acpi until kernel 2.6.21 and release

moved to the drivers/misc tree and renamed to thinkpad-acpi for kernel

The driver is named "thinkpad-acpi". In some places, like module
names, "thinkpad_acpi" is used because of userspace issues.

EXPERIMENTAL: UWB
-----------------
This feature is marked EXPERIMENTAL because it has not been extensively
tested and validated in various ThinkPad models yet. The feature may not
work as expected. USE WITH CAUTION! To use this feature, you need to supply
the experimental=1 parameter when loading the module.
sysfs rfkill class: switch "tpacpi_uwb_sw"
This feature exports an rfkill controller for the UWB device, if one is
present and enabled in the BIOS.
