millimetres.

Indeed.  Instead what we get is that on the same screen (with the
display size set correctly in the XF86Config so the dpi should be
correctly set by the X server) running at 640x480 all the text in the
gdm theme is absolutely tiny and unreadable(!!!) while at 1280x1024 all
the text in the gdm theme is huge and can be read from a plane.  Note
this is using the exact same theme...  (And all other themes I have
tried do exactly the same.)

Considering we tell X what our display size is in millimetres it should
have the correct dpi...  Certainly looking at the X server log it would
seem that it does have the correct dpi...
