Bug#481361: xserver-xorg-video-ati: No display on DVI output

[Francois Gouget <fgouget@free.fr>]

First, as I said in a previous email (which I can't find now), this 
problem is still present in xserver-xorg-video-ati 1:6.9.0-1+lenny4.

Fortunately, after some searching, I found the Git repository for my 
driver. It would be nice if this information was available in the 
xserver-xorg-video-ati package (after all we're open-source so why not 
make it easy for the user to find the authoritative source of the code).

>From there I could do a git-bisect which pointed me to this patch as the 
culprit:

Unfortunately it is somewhat long and cannot cleanly be reverted in the 
current tip. But hopefully it will point the way to the fix.
