Stuck on gray/blue screen on first boot after installation.

Hi!
Specs:
Gigabyte Z77X-D3H
i7 3770k
(Sapphire Radeon HD 6950 2Gb OC // Removed!!) -> Intel HD4000 (Processor Graphics)
16 Gb RAM Corsair Vengeance DDR3
Seagate Barracuda 2Tb
OCZ Agility 120Gb

I successfully installed Lion using UniBeast and BridgeHelper. Unfortunately, on my first boot, i'm just getting a blue screen with no mouse, or a gray screen with mouse (sometimes correct resolution) if I use some boot flags such as -x, I think this is due to my Graphics Card, but if so how can I install the correct kext without re-installing? If you think its something else, feel free to post below too
Your help is greatly appreciated! Thanks in advance

I was running into the same issue and tried typing PCIRootUID=0 and that fixed it but now I have to type that every time I boot to get video.
