I person actually found a way to legally run OS X on any computer without breaking the EULA setup by Apple. I think they made some changes to things since then so people can't do this anymore, but at one point, you could have files load before the system would check to see if it really was a mac that would prevent the check and allow the system to boot.
As for modifying the resolution, I've never heard of any way to change it outside of through the system preferences option.
