That is _A_ nouveau driver, one of several, among which:
/lib/modules/<version>/kernel/drivers/gpu/drm/nouveau/nouveau.ko
/usr/lib/xorg/modules/drivers/nouveau_drv.so
/usr/lib/x86_64-linux-gnu/libdrm_nouveau.so.2
/usr/lib/x86_64-linux-gnu/dri/nouveau_dri.so
/usr/lib/x86_64-linux-gnu/dri/nouveau_vieux_dri.so
Thus there can be no "the" nouveau driver without more information than usually
presented along with string "the".

Of course they do. N.I.H. Check the history on the page and you will probably find
that language dates back to before the modesetting DIX driver was born, and
probably before KMS too. I think I already did that check last week. The
modesetting DIX and KMS changed a lot in the many years since.

If no appropriate DDX driver is available, absent specific configuration to do
otherwise, the modesetting DIX loads and stays loaded, as long as an appropriate
KMS module is loaded and functional, which *.modeset=0 and nomodeset disable.
