Seems you have graphics acceleration but you lost the DP port according to the IOReg file. You only have the internal LCD and 1 HDMI port.
Did the wallpaper glitched with your new Config file or mine?
With my config file, does graphics not show HD540?
I see you have added DW1820a wifi in your Config file, does it work?
Last I tested it, my system hang after 10 - 15 minutes of usage.
