HD Graphics 2500 (why not?)

[meowmers]

Hello everyone,

am currently using the i3-3220 (with HD Graphics 2500).
It is not fully supported as I am only getting 1024x768 on VGA and DVI (yep you read right, VGA and DVI)

but as least i've managed to get this system working on Lion 10.7.5. Fully Boot-able.

Yesterday as I was advised to upgrade to ML so I can use my GTX650TI when it comes,
I upgraded, and my hackintosh no longer boots properly without the use of bootflag -x

Here's the biggest question that triggered from bald guy's comment somewhere around the forum:
If the 2012 iMac uses the 2.7GHz Intel Core i5-3330s with HD Graphics 2500,
why then is it not supported on our hackintosh?

All of the 2012 iMacs have a discrete graphics card in them:

21.5" 2.7GHz: GeForce GT 640M
21.5" 2.9GHz: GeForce GT 650M
27" 2.9GHz: GeForce GT 660M
27" 3.2GHz: GeForce GTX 675MX (configurable to GeForce GTX 680MX)

So they aren't using the HD2500 graphics even though the processor has the capability.
