Title:
  [Toshiba Satellite M645] Keyboard backlight does not work

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Disabling ACPI causes the keyboard backlight to work perfectly. However, this has the unfortunate side effect of disabling monitor brightness control and suspend ability (and likely other things). Is there a way we can just disable ACPI for the keyboard alone?
