It appears that Lenovo decided to break the EC brightness control interface in a weird way in their latest BIOSes. Fortunately, the old CMOS NVRAM interface works just fine in such BIOSes. Add a module parameter that allows the user to select which strategy to use for brightness control: EC, NVRAM, or both. By default, do both (which is the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use NVRAM only on Lenovo ThinkPads.

---help---
|
|
This option enables device driver support for in-band access to the
|
|
IBM RSA (Condor) service processor in eServer xSeries systems.
|
|
The ibmasm device driver allows user space application to access
|
|
ASM (Advanced Systems Management) functions on the service
|
|
processor. The driver is meant to be used in conjunction with
|
|
a user space API.
|
|
The ibmasm driver also enables the OS to use the UART on the
|
|
service processor board as a regular serial port. To make use of
|
|
this feature serial driver support (CONFIG_SERIAL_8250) must be
|
|
enabled.
