I tried the parameter "DisplaySize xx xx" in the monitor section with no 
success. A workaround is to change the font sizes, but switching between 
the "old" and "new" driver is not so nice :-)

libdrm 2.3.0-4 (debian lenny)
mesagl1-mesa-glx 2.5.2-7 (debian lenny)

Neither greedy nor always seems to help. Scrolling and moving windows is 
compared to XAA slow (too slow!). I don't need it and XAA is working fine.
