You should not expect compiled, then disassembled code to be exactly like the source code.
Compiler optimizations/etc.

Ok, so that should work for me, right? Asking cause I have one USB and I wasn't expecting to be ale to have such luck soon, and I deleted high sierra from there and got OS X 10.6 to put on an oooooold laptop for fun. I'll try ASAP though

It didn't work :( I placed SSDT-14 to patched, but I had no luck. I have it in SortedOrder. EDIT: also tried to make an SSDT-DiscreteSpoof, added to sorted order. Nothing. But I forgot to mention something: before, after the IOGraphics 0x15 0x43 line org.ntp.sntp crashed with abnormal code 175. Now it doesn't, though WindowServer still doesn't wanna start. EDIT2:deleted IONDRVSupport.kext using single user mode. STILL THE SAME. WindowServer is invincible :/

Your setup is wrong.
SSDT-14.aml has no effect since both DropOem=false and AutoMerge=false (AutoMerge=true requires my build of Clover, and you're not using my version of Clover).

This code is wrong:
Code: 
    Method (_SB.PCI0.RP01.PEGP, 4, NotSerialized)
    {

Should be:
Code: 
    Method (_SB.PCI0.RP01.PEGP._DSM, 4, NotSerialized)
    {

And the _DSM->XDSM patch is disabled in your config.plist.

Thanks a lot. I'm not experienced in DSDT patching sadly but I will try that ASAP.
