Your ioregistry shows that you have something configured that is adding nvidia information to your 9200m coprocessor:
Over the last couple years I have managed to keep my system running with my own tweaks here and there keeping it alive. For some reason though, with my 10.8.2 USB installer I am still unable to get graphics, using ANY of the new DSDTs including the latest one. For some reason when I boot into my 10.7.5 Install on the SSD ( graphics stopped working after the latest update in September) I can remote into the system using VNC but only after booting the system in safe mode. For some reason booting in verbose mode makes it kernel panic after the verbose output hits macx_swapon. Right before that line it prints NVDANV50HAL loaded and registered and then [AGPM Controller[ unknownPlatform followed again by the loaded and registered. The odd thing here is that when I am able to boot into it in safe mode with VNC, it doesn't seem to be detecting the display so I must be missing something. I can tell that the Installer for 10.8.2 has booted based on the blinking of my USB flash drive intermittently but the graphics never come up even after leaving it sit for a while (in the past the graphics would sometimes kick in automatically and the display would initialize . The problem to me seems to lie in display detection as the display doesn't even seem to power on at all now. Any input or diagnostics steps to troubleshoot would be much appreciated!

That of course will make your graphics not work.
I guess you're using GraphicsEnabler or some nvidia injector or your own custom dsdt. In post #1 the instructions were revised so that the 9200m part doesn't get any injection strings to avoid this problem.
Why don't you try to follow post #1 (see especially plists.v4.zip)?
