Public bug reported:

Binary package hint: xorg

On a Dell E6500 with intel graphics and a 1920x1080 panel, with kubuntu.

On Karmic, xorg was detecting the correct physical screen size (about
30cm x 20cm) and resolution and thus setting the dots-per-inch
correctly.

On Lucid, the physical screen size is set at over 50cm x 32cm to always
give a dpi of 96, which gives ridiculously  small fonts on this machine.
The xorg log indicates

(II) intel(0): Setting screen physical size to 508 x 317

please, avoid hardwiring the dpi to 96 since it makes no sense at all.
Why should my laptop believe that it has a screen as big as a huge TV
set?

If there are machines where edid reports incorrect data, then default to
having some reasonable dpi there, but provide a means so that one can
specify to use edid on his machine.

If this is an upstream bug with intel graphics, please be so kind to
report upstream.
