Bug#192229: xfree overwrites new driver with old each upgrade

[Tim Burgess <tim@hotu.com>]

Package: xfree86-common
Version: 4.2.1-6

Each and every time I've upgraded xfree in the last 2 years, my
X breaks. I spend 30-40 minutes reworking my XF86Config-.. and
puzzling over why it has broken, until my memory dimly recalls
that I am using the latest video driver, and this new version of
X has probably come equipped with an old driver. I'm puzzled as
to why and maybe just plumb unlucky but old drivers always seem
to break my system.

Is there some way in which a newer driver can be flagged so that
it doesn't get overwritten by an older driver? Debian package mgmt
does so much other stuff well that this would seem possible (and
should even be the default behaviour?)
