What version are you running? Leopard versions of X11 should report a hard-coded value of 75dpi, and starting with 2.3.2_beta??, it reports 96dpi:
Hmm. Don't modern displays actually communicate both physical dimensions and the number of pixels to the host computer over the DVI interface (or VGA even)? Why is there a need to hard code screen resolutions?
X11 doesn't know about the difference between multiple monitors. It is seen as one large display, so we can't say "display 0 is 96dpi and display 1 is 110dpi"
