Do keep in mind that the patching which is done to get it working (note
that patch still failed compiling for me on 4.13.2 ... no patch was needed
on 4.13.1) also has to change the license type so that it works, as a
non-GPL symbol in use was marked GPL apparently ... which of course means
it cannot be distributed by Negativo as a "fix" ...
Checking the comments on the Negativo nvidia-driver site it appears that
there's already reports of it not working on F27 with that kernel:
