719EXPERIMENTAL: The 16-sensors feature is marked EXPERIMENTAL because the
720implementation directly accesses hardware registers and may not work as
721expected. USE WITH CAUTION! To use this feature, you need to supply the
722experimental=1 parameter when loading the module. When EXPERIMENTAL
723mode is enabled, reading the first 8 sensors on newer ThinkPads will
724also use an new experimental thermal sensor access mode.
