Fine.
It's expected that brightness hotkeys aren't functional with acpi_video on
recent ThinkPads because their BIOS stop handling of the brightness and
rely on OS once acpi_video gets involved.

The acpi_video module should of cource be enhanced to handle these
brightness events defined in ACPI 3.0 spec. If I would have some spare
time...
