I suspect it has something to do with the graphics drivers though.
I'm going to try this below, I'll let you know how it goes...

Update from 10.8.2 literally killed my hackintosh. Can't boot unless using safe mode command. Did a quick fix by removing the OemSmbios.kext located /System/Library/Extensions/FakeSMC.kext/Contents/PlugIns/ work awhile but my hackintosh is not as stable as before. Downloaded 10.8.2 from app store and made new OS X Mountain Lion USB Install Disk using Unibeast.
Installation went smooth, (i did not use any commands at all). Installed latest chameleon, multibeast (FakeSMC, FakeSMC Plugins ->Motherboard Plugins)and other necessary stuff for my system. Rebooted, and voila! It can't boot.
Reinstalled OS X Mountain Lion 10.8.2 Unibeast, it also went smoothly (again without any commands). Installed saltest chameleon the again run multibeast but this time (FakeSMC/FakeSMC Plugins->Motherboard Plugins!!!!!!UNCHECKED!!!!!) and other necessary stuff for my system . Rebooted voila! Successful! Everything worked smoothly. No patches performed other than Chameleon & Multibeast. Graphics worked Out of Box, Dual Display worked Out of Box. Ran prime 95 for 11 hours, no crash or screen freeze. No
The only downside is you have to reinstall every software again. But for a rock solid 10.8.2, i think it's worth it.
Hope this can help to others with the same build.
