install these kexts from High sierra into /System/Library/Extensions:

 

AMD4600Controller.kext

ATIRadeonX2000.kext

AMDLegacyFramebuffer.kext

AMDLegacySupport.kext

ATIRadeonX2000GLDriver.bundle

ATIRadeonX2000VADriver.bundle

ATIRadeonX2000GA.plugin

 

Not sure if you need ATY_Init.kext, I didn't (I have 4850). Rebuild kextcache repair permissions and reboot.

Now you have problem with black screen, this is expected. You have to enable acceleration patches. You can now only boot in safe mode -x. You can’t apply them from Mojave, if you have multiboot, boot into your working OSX and replace the frameworks from unzipped acceler.zip (credits to @dosdude @ASentientBot and @parrotgeek1).Boot into Mojave open terminal:

sudo chown -R 0:0 /System/Library/Frameworks


sudo chmod -R 755 /System/Library/Frameworks


sudo chown -R 0:0 /System/Library/PrivateFrameworks


sudo chmod -R 755 /System/Library/PrivateFrameworks


reboot

If you don’t have multiboot, unzip and put ACCELER folder into root. Boot into Mojave recovery, open terminal:

 

mount -uw /Volumes/Mojave


cd /Volumes/Mojave/ACCELER/Frameworks


cp -R OpenGL.framework CoreDisplay.framework /Volumes/Mojave/System/Library/Frameworks


cd /Volumes/Mojave/ACCELER/PrivateFrameworks


cp -R GPUSupport.framework /Volumes/Mojave/System/Library/PrivateFrameworks


cd /Volumes/Mojave


chown -R 0:0 /Volumes/Mojave/System/Library/Frameworks


chmod -R 755 /Volumes/Mojave/System/Library/Frameworks


chown -R 0:0 /Volumes/Mojave/System/Library/PrivateFrameworks


chmod -R 755 /Volumes/Mojave/System/Library/PrivateFrameworks


reboot

Mulitboot method 100% works, recovery method not tested, but you may also try boot with -s boot arg and do analogically.
