This xorg isn't going to give you anything but 640x480

I don't think you have to worry about the vertical refresh as noted in your
previous post - if the range includes 60Hz, and your monitor wants 60Hz, I
think it'll use 60Hz.  I'm more concerned about the horizontal though -
since your numbers didn't even include the recommended rate.  I'm not sure
how to fix that, though.
