Actually, the first parameter after the name is the pixel-clock, and while it affects the horizontal sync it is not  the actual HorizontalSync  value.  My system accepts  a Horizontal Sync range starting at 30.

I raised the pixel clock to 26.9 and achieved 30.1, which made this mode acceptable (I did this remotely, so I don't know what it looks like yet) I hope it will fix the overscan problem.

Change the first paramatere to  be in the HorzSync range (or adjust the
HotrzSync range) and restart X and then look at the Xorg.0.log to see if the
720x480 is acceptable.  Then if its acceptable try to use it.
