I don't disagree with this behavior in principle, but Pawel should
really try this out with some of the common applications to ensure it
doesn't cause breakage (e.g. tvtime, xawtv, mythtv).

Despite the fact that some drivers already do this, that doesn't mean
that those drivers are necessarily the ones commonly used with these
applications.
