Bug#369624: xserver-xorg-video-mga: uninstallable on etch - depends on unavailable version of xserver-xorg-core

[Chip Salzenberg <chip@pobox.com>]

Package: xserver-xorg-video-mga
Version: 1:1.2.1.3.dfsg.1-2
Severity: grave
Justification: renders package unusable

I can't install xserver-xorg-video-mga on my etch system, which I just
upgraded from sarge.  Dselect reports:

  xserver-xorg-video-mga depends on xserver-xorg-core (>= 0.99.0-1)
  xserver-xorg-core does not appear to be available

Similarly, apt-get reports:

  # apt-get install xserver-xorg-video-mga/testing
  Reading package lists... Done

  Selected version 1:1.2.1.3.dfsg.1-2 (Debian:testing) for xserver-xorg-video-mga
  Some packages could not be installed. This may mean that you have
  requested an impossible situation or if you are using the unstable
  distribution that some required packages have not yet been created
  or been moved out of Incoming.

  Since you only requested a single operation it is extremely likely that
  the package is simply not installable and a bug report against
  that package should be filed.
  The following information may help to resolve the situation:

  The following packages have unmet dependencies.
    xserver-xorg-video-mga: Depends: xserver-xorg-core (>= 1:0.99.0-1) but it is not installable
  E: Broken packages

So, I can't run X.
