It will work except under new X.org, which disables BIOS backlight functionality in order to do it directly, at least on Intel GPUs (and probably also on ATI GPUs. nVidia is no-man's-land). And I have been told that X.org can do 256 backlight levels on Intel hardware *including* switching the backlight off, instead of just the 16 levels Lenovo chose to export through ACPI. Looks like someone should add a kernel framebuffer device for those Intels :) We really need to solve the userspace mess, though. -- "One disk to rule them all, One disk to find them.
