Good news from our friends.
One can get working acceleration (and finally a full working driver) on amd Fiji cards (R9 Fury/X/Nano)
Just add device id (0x73001002) into Baffins section (AMDBaffinGraphicsAccelerator) in /System/Library/Extensions/AMDRadeonX4000.kext/Contents/Info.plist
Caveat – so far it only works on nmp as eGPU, some code that is checking for nmp is in place.
