I don't know how it is possible. After I installed the system I moved every graphics kexts into a folder and the one which I uploaded here is from there. How can I get a clean one if not from my system?
That's right. But your kext has this line: 02 00 00 00 40 00 00 00 09 01 00 00 20 01 00 03. No original Apple framebuffer has this connectors layout. But Truckers modified kext from OP has it, that's why I think this is not original kext.
You can actually try to boot even with original kext with framebuffer which is the closest to your connectors data, maybe it will work. You can try GraphicsEnabler=Yes and ATIConfig=Elodea, for example.
