What Ben means is that the nouveau driver really doesn't support
operation without KMS (kernel modesetting) any more. Both 'nomodeset'
and 'nouveau.modeset=0' do the same thing: they disable KMS. So this
method of operation is indeed entirely unsupported, no matter which
kernel parameter you use to initiate it.

(are you actually using the nouveau driver in this case? Or VESA?)
