This bug affected nv only.  nouveau was not affected.

Broadly speaking the nouveau driver is widely reported to have equal or
better 2D performance than nv, occasionally even on par with nvidia.

Only if you're lucky.  There are deep issues with the nv resume path;
essentially VBE doesn't work reliably after suspend, so the only way to
reinit the card is to execute the nvidia equivalent of what ATI calls
ATOMBIOS.  The nouveau driver contains a start towards implementing
this, but it's not done.  I don't know if anyone is owning that feature,
it would certainly be a welcome area for contribution.

Maybe.  Certainly not in Fedora as shipped, we're not shipping the 3D
part of the driver yet due to immaturity (of the driver, not of the
developers).
