So can we assume that what he has done here is to take a working initramfs with the nouveau module loaded (albeit a 3.14 kernel) and
runs it at bootup time and the system can also find
/usr/lib/modules/3.14.0-200.fc20.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko and that is why nouveau is working again?  Are we
sure that the 3.16.3-200 initramfs (original) was, in fact for the 3.16.3 kernel or could it be that that initramfs was also screwed
up (much like the 3.14.0 / 3.14.9 debacle) and *that's why when he was trying to insmod
/usr/lib/modules/3.116.3-200.fc20.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko  it couldn't load the module?  If one initramfs
got screwed up whose to say they *all aren't screwed up?  And if that's the case then there is no way that Fedora would be able to
automagically figure out loading of modules, etc.
