Yes please :)

When the GSP did not bring anything to users because the userspace was 
unable to really make use of it, I think it made sense to keep it disabled.

The situation has however changed quite drastically and at this point, 
not using the GSP has a big impact on usability. And users who do not 
wish to depend on a proprietary firmware can always use 
`nouveau.config=NvGspRm=0` to disable it (if they can't find a Kepler 
GPU that would be supported using only open source firmware).

I would however appreciate better error reporting when loading the GSP 
fails, as it can currently be quite unhelpful without increasing the
drm log verbosity:

	[    2.177205] nouveau 0000:01:00.0: gsp ctor failed: -2
