Hi there
Let me add my two cents on the Toshiba side.

With Toshiba we have two types of hardware implementations:
1st gen keyboards, supporting AUTO and FN-Z AUTO - Turns on/off automatically after some (configurable) time FN-Z - Creates "toshiba::kbd_backlight" and it's toggled by userspace
2nd gen keyborads, supporting AUTO, ON and OFF AUTO - Ditto ON - Always on OFF - Always off
The second gen keyboards are completely driven by hardware, userspace must be checking sysfs for "kbd_backlight_mode" changes, however, the Toshiba interface emits the 0x92 ACPI event when we have a kbd mode change, but it's not currently being transmitted to userspace via netlink.
