New X upgrade in unstable makes fonts too big

["Edward C. Jones" <edcjones@comcast.net>]

I have a PC with an AMD Athlon64 chip and Debian unstable, i386 port. My 
monitor is 1024x768. It is 328mm by 246mm (17 in).

Today (April 11 2006) X was upgraded in unstable. Now all my fonts are 
much bigger.

Some of the lines returned by "xdpinfo" are:

version number:    11.0
X.Org version: 7.0.0
screen #0:
  dimensions:    2032x1530 pixels (321x241 millimeters)
  resolution:    161x161 dots per inch

Here is part of my "xorg.conf". Note the "Virtual".
SubSection "Display"
    Depth        24
    Modes        "1024x768" "832x624" "720x400" "640x480"
    Virtual      2032 1530

If I comment out the "Virtual" line and restart X, the fonts are much 
smaller. It looks like the "Virtual" line is being used (incorrectly) to 
set font size. What is the problem and what should I do?
