I also just found the manual for another Thunderbolt equipped motherboard, in this case it's the "MSI Z77A-G45 Thunderbolt LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS" which you can find at http://us.msi.com/service/download/manual-19309.html. On page 1-4, it states: 1x Thunderbolt port** (Mini DisplayPort), supporting a maximum resolution of 2560x1600 @ 60Hz.
This also suggests that the video signal should be compatible to me. Though I did think of something...Mini DisplayPort and Thunderbolt both support the 2560x1600 resolution I believe. So, is it possible that these specifications on these boards might suggest that it would work with Mini DisplayPort (and therefore NOT Thunderbolt)?

Well, according to another Apple Senior Tech, they looked in to it and stated that the firmware on the LATEST (Late 2012) iMac will not allow this to happen. Even if the motherboard is compatible and is broadcasting video, the iMac will not allow the signal to be compatible with the iMac. It's almost as if Apple figured someone like me would try and do something like this and figured, "nahhh...let's make him buy an additional cinema display or something."
Anyhow, back to the drawing board I guess. It just doesn't make sense to have a 27in iMac/Display sitting on my desk but not be able to use it as an external monitor for other various devices. Having two 27in displays sitting next to eachother is excessive for something like this. Frankly, having a second display of any size just doesn't make practical sense with the 27in iMac there. This is why I'm so ****-bent on finding a way to get native Windows (non-boot camp) on my iMac display that can handle things like modern PC Games like Battlefield 3, etc.

I understand you. I feel the same. Hope someone will find a way to do this.

Ahhhh! This is so frustrating! Why wouldn't they let us do that?! It just seems like a feature few would use so it wouldn't really hurt anyone but certainly inspire good faith in the customers.
You can connect an Air through thunderbolt without a problem, so there HAS to be someway to trick it to work with a PC as well. Maybe someone could hack the driver or something....

The only other thing I can think of is if we could downgrade the firmware of the late 2012 iMac to the previous version which would very likely allow for PC Thunderbolt output...but that's not a forward-thinking solution and will only work for so long.

Doesn't work in Bootcamp either.
Only thing we can do now is ask Apple real nicelly to update Target Display Mode here.
