Bug Description
Newer Thinkpads have 16 levels of backlight control, but thinkpad-acpi is unable to provide most of them. This makes it impossible to set full brightness. The ACPI video interface provides full access to them, and so thinkpad-acpi should refuse to bind in the case of the video extension being present.
