Bug#407671: Missing CONFIG_PMAC_BACKLIGHT_LEGACY breaks backlight control

I have to agree with Matthias here. The same bug happens for pmud which I
haven't converted to sysfs yet. The kernel should not introduce changes
that break backwards compatibility, ever. Doubly so for the stable release

Fully agree. Thanks to Matthias for explaining the severity nicely. Now
can we have the bug severity reset, please? Can we have the reason for
disabling this option explained?
