XFree86 V4 checks the monitor and asks it what its DPI is at a given
resolution. If that doesn't work, I believe you can set it in the config file
with Option "DPI" "98x98" in the "Screen" section.

It's not just scaling things up -- internally, the graphics system should
really be using points internally. Even at the default X resolution, 75 DPI, a
pixel is not the same as a point -- it's merely close. At 75dpi, assuming
square pixels (not always assured), a point is 1.041667 pixels.
