As requested by RehabMan, I'm making this thread so we can hopefully find a solution about a strange Broadwell graphics issue.
So, I have an HP laptop (full specs in profile), which seems it will never have it's graphics working under OS X/macOS. Before you reply to this thread, no, it's not the typical DVMT pre-allocated memory issue that you will find on all laptops since Broadwell. This problem only exists on some laptops and I can't figure out what's causing it. So, if you happen to have one of these "weird" Broadwell laptops, you will face a strange hang and sometimes, KP, if you try to inject the graphics with a valid ig-platform-id. If you remove the kext that provides acceleration, AppleIntelBDWGraphics.kext, NOT AppleIntelBDWGraphicsFramebuffer.kext, then your laptop will boot fine with correct display detection, VRAM info, backlight control etc...
Here I have some links about the same issue found on several laptops:

I attach my CLOVER folder and some verbose pictures showing three different KP's and a "hang". As you can see, it doesn't always throw a KP, sometimes it's just a hang on the [IGPU] messages. In other words, the KP/hang varies.
Notes:
1. I don't really have to remove AppleIntelBDWGraphics.kext to boot. I can just boot in safe mode to eliminate the kext from loading.
2. I have tested all DVMT pre-allocated and DVMT-size options.
I hope I describe the problem clearly.
