Public bug reported:
Binary package hint: acpi-support
/etc/acpi/thinkpad-brightness-[down,up].sh is a no-op on Lenovo laptops,
but as we can see in acpid logs[1], whenever the brightness up/down keys
are used, /etc/acpi/video_brightness[up,down].sh is called, and that
script is identical to the first one, except that it doesn't special
case Lenovo laptops.

Also, if you don't have the 'video' module loaded, the "video LCD0
00000086 00000000" event is not fired and thus the brightness keys don't
work. For some reason that module is not loaded on bootup for me and so
the brightness keys don't work on my T60.
