Edit://
Sorry for the noise. It was completely my misunderstanding of the situation. All is fine, libgl1-nvidia-alternatives, libglx-nvidia-alternatives have to go with nvidia v 304.88-3.
Ignore the following.
----------------------------------------
(I don't understand this situation but we should wait:)
Edit: we need to d-u manually the nvidia packages:
# apt-get update && apt-get dist-upgrade -d
...
Paketaktualisierung (Upgrade) wird berechnet... Fertig
Die folgenden Pakete werden ENTFERNT:
libgl1-nvidia-alternatives libglx-nvidia-alternatives
Die folgenden Pakete werden aktualisiert (Upgrade):

and
# apt-cache show nvidia-alternative
Package: nvidia-alternative
Source: nvidia-graphics-drivers
Version: 313.30-1
Installed-Size: 156
Maintainer: Debian NVIDIA Maintainers <pkg>
Architecture: i386
Depends: glx-alternative-nvidia (>= 0.2), libgl1-nvidia-alternatives (>= 275.09.07-4), libglx-nvidia-alternatives (>= 275.09.07-4)
Breaks: libgl1-nvidia-glx (<< 275.09.07-2), nvidia-glx (<< 275.09.07-2)
but version
# apt-cache policy libgl1-nvidia-alternatives
libgl1-nvidia-alternatives:
Installiert: 304.88-2
is installed.
OTAH, there is this situation:
# apt-cache policy nvidia-alternative
nvidia-alternative:
Installiert: 304.88-2
Installationskandidat: 304.88-3
Summery: the situation for nvidia geforce 6xxx/7xxx is a mess as nvidia does *not* care about the right dependencies for those chips. We have to install the needed packages *manually* and take care to *manually update* those packages and then mark them to be hold.
Any advice to automagically d-u those packages is welcome.
