I generated an xorg.conf file with "Xorg -configure", and modified it to
contain  "DisplaySize 285 215" in the Monitor section. (The generated file had
"#DisplaySize 290 210", commented out.)  Xorg.0.log now contains 

  (II) RADEON(0): EXA: Driver will not allow EXA pixmaps in VRAM
  (**) RADEON(0): Display dimensions: (285, 215) mm
  (**) RADEON(0): DPI set to (124, 124)
  (II) Loading sub module "fb"

However, xdpyinfo still says the monitor has 96 dpi, and KDE still uses small
lettering.
