Since CONFIG_ACPI_VIDEO wasn't required before 2.6.26.x to change the LCD brightness, I'd rather the kernel go back to whatever it was doing for 2.6.25.x. Upgrading X past what's currently packaged by the distribution just to get a new kernel working is somewhat of a pain.
What change linked the brightness keys to CONFIG_ACPI_VIDEO?
