While the problem isn't fixed, you can try forcing thinkpad-acpi to provide a backlight interface and use that (docs in Documentation/laptops/thinkpad-acpi.txt). But you get to keep both pieces if that causes the kernel or X.org's GPU drivers to blow up in pieces when the SMBIOS messes with the GPU behind their backs. -- "One disk to rule them all, One disk to find them.
