Eduardo, nvidia-common has no relation to jockey-common at all. jockey-common merely recommends nvidia-common, just like fglrx-modaliases.
A strict dependency is too much, since it should be possible to install Ubuntu without non-free drivers, and jockey doesn't depend on fglrx/nvidia at all. The latter just provide drivers which jockey can handle.
