Not an X bug, needs to be fixed in the kernel.

On a guess, I'd say that it's only a hardware lock for the LED, not for the touchpad itself. And the kernel doesn't (or can't?) query the state of the lock.
And it seems the kernel may not get the "on" event, only the "off" event. Hence this weird sequence of events. Only guessing here though.

Either way, there's nothing we can do in the X drivers until we get the right sequence of events.
