[Bug 282620] [NEW] [thinkpad-acpi] for t43 should be set brightness_mode=1 (EC)

[fishor]

Public bug reported:

By default thinkpad-acpi use brightness_mode=3 (EC & NVRAM) for all
thinkpads. But this not working correctly with thinkpad t43, brightness
is controlled by hotkeys but not by userspace tools.  instead
brightness_mode=1 (EC only) should be set to work properly. So after
this brightness can be controled bay hotkeys and userspace tools.
