The GIT commit reversion should be similar enough to a manual change I tried with both 4.9 and 4.10 I can almost certainly say it would work (trying the old firmware manually). I haven't tried the other, and won't be able to for about 5 hours (away from the desktop in question).
So the new firmware works in 4.10, but not in 4.9?
The old firmware works in 4.10. The new firmware hasn't been tested by me outside of 4.9.
