Why the audio layout-id is affecting your screen is beyond me. Unless when you pick a different layout-id it causes your laptop not to boot and that's what you're referring to as the black screen?
Either way, your way doesn't work for anyone else lol.

For you guys that you have still problems, can you try going into sysprefs> display and change resolutions back and forth, see if the screen gets stuck on black screen after a few tries.
Im curious to know that...

Update on my end.
I came across a fork of Whatevergreen by @Fraxul from here that has a patch he just applied to it. So far I'm 10/12 reboots with working backlight and only 2 that went to a black screen upon boot up. This is the best working to not working ratio I've had thus far.
The fork is here: https://github.com/Fraxul/WhateverGreen/tree/1e92070d4d22a832492f339f05ad814c20efddb1
(I pasted the wrong link when I first posted this comment. My bad if you used the original link)
@black.dragon74 you might want to check this out and see if there are any changes for you.
I'm going to do some more testing and see what happens. The big tell all here will be if the random freeze/crash that has been happening because of this framebuffer issue is gone or not.
Attached PR files incase anyone wanted them.

So
Here I described the problem I had with the latest build of whatevergreen and Lilu.
With that I can finally have full brightness and the slider in settings is working just fine. Then I realised that every 1/4 of boot I got black screen and then after 3 minutes as always is gone. So I removed the SSDT-PNLF.aml but not the kext. At the next reboot I found out that I have the same brightness than before the reboot. I can't modify it because there is no slider, I thinks that is because I removed the .aml patch. For the people that haven't resolve the 3 minutes black screen yet this can be helpful.
For my case I hope in your help
Ps: I would like to have the slider and also the max brightness higher just like in the installer as described in my other post
