I used to use the nomodeset. I also tested for it and brute-force switched
between Nouveau and Nvidia legacy based on it. I have not had nomodeset since
that "trick" (copying one or other Xorg.conf) became deprecated and I did a
new 64-bit install.
With no appends on kernel command line, Xorg works with either driver until I
try to use KDE, Kwin, compositing. Then Nouveau will hang up, Nvidia legacy
304 will have missing window decorations.
