Ok...so I found that my display is running at 75dpi (bad for fonts). However,
the howto up on mythtv.info is very vague:

Does anyone have advice to give on how to accurately determine and specify your
displaysize in xorg.conf?
1) You can start X with a command-line option:
startx -- -dpi 100
(won't work if you need different horizontal and vertical DPI).
2) You can calculate the appropriate "DisplaySize" based on the
resolution you're using:
Given 1 inch = 25.4millimeters
DisplaySize is specified in millimeters
You're using a resolution of X x Y:
DisplaySize should be set to the truncated integer value (note, you have
to do the math yourself, don't specify the equation in your X
configuration file):
DisplaySize: ((X / 100) * 25.4) ((Y / 100) * 25.4)
So, for 1024x768:
1024 / 100 = 10.24 * 25.4 = 260.096 = 260
768 / 100 = 7.68 * 25.4 = 195.5072 = 195
DisplaySize 260 195
Some round instead of truncating. I've found that truncating gives best
results...
