There graphics is not loading because you didn't set the DVMT, but that's okay, I have the patches in place. Only problem is it won't work during installation because the graphics kext needs to be cache. So to get the installation going, you need to boot with no graphics support by adding boot arg -igfxvesa
So when you boot to Clover, press the letter O. This will bring you to Options.
Go down to the boot arg line and add -igfxvesa
Now go back to the main menu by hitting the escape key or click on return
Continue booting to the installer
