Except you're still not running at 1400x1050, because as the log says, your 
screen's virtual size is 1280x1024.

If you'd force the screen size to 433mm by 347mm you'd be much closer to 
actual 75dpi.  But I expect it'll still look bad, because you're not using 
the native panel size of 1400x1050, so the panel will interpolate and defeat 
freetype's antialiasing.

Dear intel, users want working modesetting, kthxbye.
