Apple seeded a fourth Beta (OS X 10.11.1) to Developers and Public Beta tester, and this update (Build 15B38b) adds support for Intel Skylake processors. Here are the used board-id/model combinations that you may find interesting:
board-id: Mac-65CE76090165799A – Model: iMac17,1 (Retina 5K, 27-inch, Late 2015) / Core i7 4.0GHz
board-id: Mac-B809C3757DA9BB8D – Model: iMac17,1 (Retina 5K, 27-inch, Late 2015) / Core i5 3.3GHz
board-id: Mac-DB15BD556843C820 – Model: iMac17,1 (Retina 5K, 27-inch, Late 2015) / Core i5 3.2GHz
Edit: iMac16,x model/board-id’s removed (Broadwell models).
Kernel support for Skylake is checked like so:
ffffff80003c477c cmpl $0x5e, %eax
ffffff80003c477f jne 0xffffff80003c47b1
ffffff80003c4781 jmp 0xffffff80003c47a0
../..
ffffff80003c479b cmpl $0x4e, %eax
ffffff80003c479e jne 0xffffff80003c47b1
ffffff80003c47a0 movl $0x37fc219f, %ebx ## imm = 0x37FC219F // CPUFAMILY_INTEL_SKYLAKE
The previously missing power management files are now also there:
/S*/L*/E*/IOPlatformPluginFamily.kext/C*/P*/X86PlatformPlugin.kext/C*/Resources
Edit: Apple apparently started to use _CSS and _PSS instead of the previously used Apple specific ACSS and APSS. About time.
More importantly. There are new kexts added for graphics support:
AppleIntelSKLGraphics.kext
AppleIntelSKLGraphicsFramebuffer.kext
AppleIntelSKLGraphicsGLDriver.bundle
AppleIntelSKLGraphicsMTLDriver.bundle
AppleIntelSKLGraphicsVADriver.bundle
AppleIntelSKLGraphicsVAME.bundle
Intel10SeriesAHCI support has also been added:

And here are some interesting snippets that I added to RevoBoot:
#elif (TARGET_MODEL == IMAC_162)
// Intel Core i5-5575R @ 2.8 GHz & Intel Core i5-5675R @ 3.1 GHz

Yesterday I added two new models to my blog article about Apple Serial Numbers Ending With G000-GZZZ and today Apple published a lot more so now we have 24 new iMac models listed:
GF1J – iMac (21.5-inch, Late 2015)
GF1K – iMac (21.5-inch, Late 2015)
GF1L – iMac (21.5-inch, Late 2015)
GF1M – iMac (21.5-inch, Late 2015)
GG77 – iMac (21.5-inch, Late 2015)
GG7D – iMac (21.5-inch, Late 2015)
GG7G – iMac (21.5-inch, Late 2015)
GG79 – iMac (21.5-inch, Late 2015)
GG7C – iMac (Retina 4K, 21.5-inch, Late 2015)
GG7F – iMac (Retina 4K, 21.5-inch, Late 2015)
GG7H – iMac (Retina 4K, 21.5-inch, Late 2015)

GQ17 – iMac (Retina 5K, 27-inch, Late 2015)
GQ18 – iMac (Retina 5K, 27-inch, Late 2015)
Note: The Intel i5 (1,6HGz, 2.8GHz and 3.1GHz) are Broadwell based.
Now you have (almost) everything to setup your Intel Skylake based Hackintosh 😉
Update I renamed AppleIntelFramebufferAzul.sh to AppleIntelGraphicsFramebuffer.sh and added support for the Intel Skylake processor graphics – new version soon the be released – and here is some of the output.

Edit: The IOPCIPrimaryMatch list in AppleIntelSKLGraphicsFramebuffer.kext/C*/Info.plist does not include 0x191b.
Edit-2: The following frame buffer data is currently still inactive:
0x19020001 – Skylake Desktop GT1
0x19170001 – Skylake Desktop GT1.5
0x19120001 – Skylake Desktop GT2 (duplicated/used twice)
0x19320001 – Skylake Desktop GT4
None of these will work so there is no point of using them. Also note that 0x19120001 is used twice and I changed the second one into 0x19120003 and used it during my test runs, but whatever I did, my monitor always showed up on port 6. I can change the port number, and all the rest of the values, but I can’t seem to change the third port without breaking stuff. Pretty weird.
