[Bug 623495] [NEW] Fn + Z doesn't change BIOS backlight keyboard policy in Toshiba Laptops

Public bug reported:

Fn + Z should switch between the different backlight keyboard modes as defined in the BIOS.
I've seen this problem in both a Toshiba Qosmio X500 and Satellite M640 with backlight keyboards. In this last model (Satellite M640) the keyboard doesn't light up even with the BIOS option set to always on.
