I can confirm that this issue still exists in the following configuration:

- On-Board Radeon chip; lspci info:
   01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200
Graphics
- Monitor: Samsung SyncMaster 2333SW (vendor "SAM", prod_id 1246)
- radeonhd driver 1.2.5
- xorg-server 1.6.1.901 (from experimental)

* Symptoms

- ddcprobe shows correct dimensions: "screensize: 51 29"
- Xorg seems to know proper size (from Xorg.0.log):

(II) RADEONHD(0): Max Image Size [cm]: horiz.: 51 vert.: 29

- But later it somehow comes up with incorrect numbers, which
  propagate into xpdyinfo:

(II) RADEONHD(0): clock: 138.5 MHz Image Size: 477 x 268 mm

- xdpyinfo:

  dimensions: 1920x1080 pixels (477x268 millimeters)

- xrandr has the wrong numbers as well:

  DVI-D_1 connected 1920x1080+0+0 (0x3d) normal (normal left inverted right x
axis y axis) 477mm x 268mm

I tried adding the monitor to quirk_detailed_use_maximum_size(), but
that didn't change anything.
