Hi,
In Precise kernel, it already provided an interface to turn on/off the tourchpad LED /sys/class/leds/dell-laptop::touchpad/brightness
Other patches are just quirks to add more machines to have this interface, so I don't think it's so urgent.
The problem is that there is no userspace app to take care of this interface, and to turn on/off the LED while touchpad toggle events happened.
It's not suitable to let driver handle this, for it can't access the led subsystem while receiving the key events.
