Possible workaround: The nvidia-glx(-legacy) package should collide with the usplash package, so that the package management refuses to install both. At least this prevents users from screwing up their systems accidentally. This workaround is fairly easy to apply because only the "control.stub.in" file has to be edited. Just add a "usplash" to the corresponding "Conflicts:" line of the nvidia-glx(-legacy) package description.
