With the nouveau.ko module, yes. You have to prevent that module from
being loaded, or use nouveau.modeset=0 to disable kernel mode setting.

Yes, but this means that Squeeze's udev works as designed and Lenny's
does not, because it actually *should* load nouveau.ko if you have an

Well, the lenny-backports kernel had better stop shipping the nouveau
module, since it does not do any good without a suitable X driver.

The nv driver does not work correctly with kernel mode setting, that's
why the Squeeze version of nv refuses to load. The Lenny version of nv
does not, messing things up as you had noticed.

Not for people who have xserver-xorg-video-all installed and do not
specify a driver in xorg.conf. That's the default actually.

Yes, you have to use xserver-xorg-video-nouveau (or -fbdev, that's the
only other option) if nouveau.ko is loaded and kernel mode setting is
