You need to properly specify the display's aspect ratio in X. This
means that you cannot specify 100x100DPI (because your display does not
have square pixels). This will not be a problem with 0.21 (which
doesn't need 100x100DPI), but until then, you may see a few places where
graphics and text don't line up correctly or fonts seem to be the wrong
and ignore the 100x100DPI parts. Instead, use 100DPI vertical. (I.e.
"DisplaySize 346 195").
