This is from the edid.

(II) RADEON(0): Setting screen physical size to 508 x 317
This is from the xserver. The display size is all handled in the
xserver rather than the driver. All the driver does is pass the edid
along. Recent xservers default to 96 dpi.
Also discovered that removing xorg.conf (with HD 4850) gives me 96 DPI
instead of (correct) 82 DPI.
Restoring my xorg.conf gives me back the correct 82 DPI. File attached.
Thanks,
