In all cases, AppleIntelSNBGraphicsFB.kext/HD3000 loaded. Your HDMI1 is port 0x6 (DP), HDMI2 is port 0x5 (DP) and DP is port 0x07 (HDMI). All three connectors in the framebuffer need edits.
It seems to be working.

would you check if physical connectors are mapped to the right framebuffer connectors?
- av-signal-type = 8 + connector-type = 8 for both port 0x5 and 0x6 (hdmi 1 and 2)
- av-signal-type = 8 + connector-type = 4 for port 0x7 (mini DisplayPort)
Installed nVidia Quadro NVS 295, plugged Apple Cinema Display in NVS, BIOS primary display IGFX, GraphicsEnabler=No and everything's working (attached ioreg acd in NVS).
USB audio and iSight camera working (Apple Cinema Display).
Still my initial problem remains: Apple Cinema Display doesn't work with integrated graphics via Mini DisplayPort. I assume it's not related to hdmi, simply I guess it's not supported by Zotac Itx Wifi board (it doesn't work in bios nor in Windows 7 and Windows 8).
Beside this, do I need anything else to do?
Toleda, I really thank you very much.
