Modes is not used anymore these days. As all RandR 1.2 driver do, the 
ati driver 6.7.197 queries the supported modes and chooses by default 
the "preferred" one given by the hardware if it exists. The preferred 
one has a "+" in the xrandr output (but I guess the PreferredMode given 
in xorg.conf will override this "+" too).

Actually, we already have a NEWS entry about this in 
xserver-xorg-video-ati 6.7.197 pointing to 
http://wiki.debian.org/XStrikeForce/HowToRandR12 and 
http://www.intellinuxgraphics.org/dualhead.html.

I think we should add a NEWS entry to xserver-xorg before lenny is 
released, and a README.Debian pointing to the same URL. I am retitling 
your bug accordingly.
