Thanks.  It seems the problem is that there is no EDID information with
the 1.0.7 version of the driver.  Compare the 1.0.1 log:

with the 1.0.7 log:

Now I don't really have an idea why this happens. :( Could you please
try the 1.0.6-1[1] and 1.0.4-1[2] packages from snapshot.debian.org so
that we can narrow down in which version the regression first occurred?

Cheers,
       Sven
