I have very little time to explain what I did, but here is one of the framebuffers that works for me – edit the frame buffers for your setup, follow the links under ‘See also’ for additional information.
Note: 0x0d220003 is just an example – my first Haswell boot was done with 0x0c260000 (see also: Intel HD4600 with full resolution) but I changed it to 0x0a160000 the same day (see _DSM method) but now I let RevoBoot inject 0x04120000.

0008 0000 = HDMI
0002 0000 = DVI
Tip: VRAM (Video RAM) is not the (UEFI) BIOS settings. That is ‘fStolenMemorySize’. Representing the amount of pre-allocated DRAM memory to support the IGPU in VGA (non-linear) and Native (linear) modes. Not that you need it, because VGA is disabled.
Update
Still not perfect, but this one is getting close:

That should get you started:
1.) No boot loader changes!
2.) No reboot.
3.) No frame buffer crashes.
4.) Boot with single DVI/HDMI/DP connector possible.
5.) Connects to pipe 0.
6.) APPL,boot-display property (Boolean) set to True.
7.) IOFBNeedsRefresh property (Boolean) set to False.
