The same happend here. In Lion it would say Intel 7 series, and in ML it sas unknown ACHI Standard Controller. But I noticed that the screenshots
tonymacx86 posted here on the site regarding ML and the Ivybridge/HD4000-support show the same "unknown ACHI Standard Controller".
This is because in Lion most of us where using BridgeHelper which injected a missing device id in AppleAHCIPort.kext. I wrote a legacy kext which does the same, benefit is that you don't have to repatch AppleAHCIPort.kext after a system update. Just install this with KextBeast, KextUtility or anything else into /S/L/E.
For those of you having problems with dual monitors and HD4000, have a look at my thread: http://www.tonymacx86.com/mountain-lion-desktop-support/61216-10-8-how-enable-hd4000.html
Some user have reported to me that with using ig-platform-id of 01620005 they were able to use dual monitors on DVI and HDMI.
