Did the idea of emitting Morse code on the keyboard LEDs during kernel panics ever get working, and included in the kernel?

I'm thinking of the LWN article “Morse code panics for 2.6.29-rc1” (2003) https://lwn.net/Articles/21858/

As an aside, I haven’t seen a Tux icon on the top-left of a screen in a while. Do they still have as many Tuxes as cores?

Will that be true with the DRM kernel panic screen?
