Watching this discussion is like watching a puppy chase its tail :-)
Minus the fact that we've seen this discussion before, and we've seen it go nowhere before, just as it is now :-(
Except that it's spiraling around the drain even faster than usual :-(
I understand people do not find the current situation ideal.
As of today, however, the only laptops you can buy *new* with a *modern chipset* that are remotely reasonable for coreboot are chromebooks. This simple fact is why I came to Google.
To do a laptop port you really need to interact with an EC. The EC has been a problem for years. If you want a sane EC (i.e. 32-bit, not some 8-bit POS emulating an 8051) and you want open source software for that EC and you want coreboot ... you're going to get a chromebook. And those three things, as we have learned many times, are pretty essential to a port, unless you want to spend 3 or more years on the port.
I've got a student coming in January and he's going to work on ChromeOS on AMD CPUs, starting with the Gizmo. If, at that time, someone has a suggestion for an AMD laptop which might be suitable, let me know.
