I have a similar issue. The Front Operation Panel LED keys do not work
on my Toshiba Qosmio F60. These are handled by quickstart it seems which
are handled in Windows by PNP0C32 (Direct App Launch)

Title:
  [Toshiba Satellite A660-0T4] Topmost keys all produce the same
  scancode

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Toshiba satellite A660 backlight just never worked on ubuntu.

  Here is an outline of some of the LEDS in a toshiba

  http://i.imgur.com/l54s5CP.jpg

  When i press Fn+Z the ubuntu keyboard LED notification shows up,
  however nothing changes.

  so i navigated to

  /sys/devices/pci0000:00/0000:00:1c.4/0000:16:00.0/firmware_node/subsystem/devices/TOS1900:00/leds/toshiba::illumination/device/leds/toshiba::illumination

  found files

  brightness device max_brightness power subsystem trigger uevent

  when i changed the value in brightness from 0 to 1

  LED 1, 2, and 3 in the above picture turns on, and led 1 turns off
  when touch bad is off.

  However there is no keyboard backlight.upon boot the backboard
  backlight works while posting and shutdown when grub loads. When i
  disable acpi the keyboard backlight works however ill lose other
  functionalities like brightness.

  Any way to fix it?

  There is also another directory.

  /sys/devices/pci0000:00/0000:00:1c.4/0000:16:00.0/firmware_node/subsystem/devices/TOS1900:00/leds/toshiba::illumination/device/leds/toshiba::illumination/subsystem/mmc0::

  with files brightness device max_brightness power subsystem trigger uevent
  nothing happens when brightness value changes.

  #Problem also exists in older version of ubuntu, new kernel in 13.04
  does not solve the problems.

   xev shows a key being pressed and being mapped to kbdbacklight. A a notification that keyboard is being turned on appears when Fn+Z is pressed. Also unlike other manufactures toshiba doesn't have brightness on backlit keyboards, its either on or off or a timer.
