It probably would be better to say "nv" driver in this case. My
understanding is (someone correct me if I'm wrong here) that nouveay
"driver" is just a wrapper that figures out what video chipset you have
and loads appropriate open source driver (nv in this case) for that
chipset.

And indeed, nvidia proprietary driver "will work better" for less trivial
cases. E.g., if you attach two screens with different resolution. open
source driver will not handle it, whereas proprietary driver will. This is
why I, to the contrary to majority of Linux folks, never favored nvidia.
ATI (at least before they were bought by AMD) and matrox were disclosing
much more detail about their chips, thus providing to open source
developers sufficient information about chip internals to write decent
driver. I also am set off by many people saying "recompile nvidia driver"
for new kernel. It is not the driver you are recompiling. It merely is the
interface between precompiled by Nvidia binary driver and different
kernel.
