[Bug 76274] Brightness Settings Don't Work

[Paul Campbell]

Public bug reported:

The brightness settings as set in System Preferences > Power Management
don't make any difference whatsoever to the brightness when changed.
Either when using AC or battery.

However, using the function keys I can succesfully change the
brightness.

This on a Sony Vaio S4XP/B using Edgy.
