Public bug reported:
It seems like ever since a system update earlier this week (one that
updated a number of things, but acpi packages stuck out), my Fn keys no
longer control the brightness.
Up until that update, Fn+F6 and Fn+F7 would decrease and increase the
brightness, respectively. Now it can be controlled with the Power
Manager, but not through the Fn keys. Again, this worked correctly
until a recent update.
I have a Toshiba P200-ST2061 (Santa Rosa guts).

It makes me think that the problem is with acpi and not with hotkeys,
but I'm leaving it undesignated since I'm not an expert.
Any other information can be provided upon request.
