These modes are picked by xac (and probably the X server as well)
because if you look at the EDID reported by your monitor, these are the
modes it supports:
     ET: [[720, 400, 70], [640, 480, 75], [640, 480, 67]] (the last
640x480 comes from the "DT" section which is the detailed timing)

How is your monitor attached? Does it produce a correct EDID elsewhere?

I looked up the model # (from the EDID) and it appears that you are
correct in using a 1024x768 default (although the manual suggests a 75Hz
refresh). In light of this, I would completely remove the "Modes"
section and "UseModes",  "HorizSync" and "VertRefresh" lines from your
xorg.conf and keep the screen size at 1024x768. I would also add the the
line:
    Option "IgnoreEDID" "True"
to the "Device" section to force the driver to ignore this incorrect
edid information.

Now, in the second email, it appears that X is starting properly,
perhaps there is an issue with your wm/desktop. Can you install a
minimal wm (like fluxbox or twm) and put that in your .xinitrc, then run
startx again? Does this bring you to a working desktop?
