I hope so, but as long as nouveau is in staging there are no guarantees.
And while the nouveau developers have avoided breaking the kernel drm
ABI since Linux 2.6.34, libdrm-nouveau still changes API and ABI
willy-nilly, of course without ever altering the soname. :-/

It's hard, because that requires to have multiple versions of
libdrm-nouveau present as well (possibly inventing your own soname), and
if you happen to have the 3D driver installed (package
libgl1-mesa-dri-experimental), the X server might load two versions of
libdrm-nouveau and crash.

I think the real problem was that Fedora and the Neauveu community are
acting incredibly selfishly. They only care about their narrow point
of view, and don't care about the pain they are inflicting on the
kernel development process and other kernel developers. This is
_legal_. It is, however, anti-social. -- Ted Ts'o
