The old radeon driver (back in the xfree86 days) did know that my
laptop’s screen was 12”×9”.  I originally added --dpi 133 to my X
startup scripts only because the integer conversions between inch
(for dpi) and mm (for dimensions) led to rounding errors.

To the Reporter:  you may need to add --dpi 124 to your startup
scripts to get accurate sizing with the current X server.
