When I omit the HorizSync and VertRefresh lines, I am reduced to 640x480. Here's the problem (an excerpt from Xorg.0.log):

So Xorg is using really bad (cautious?) default values for hsync. Perhaps it works on your box because Xorg manages to successfully query the screen about its capabilities, which we have already seen doesn't work on mine.

The first 10 or so results from Google contained the following values for DXS:1313 monitors (all in Xfree86 config files):
HorizSync 30-60 VertRefresh 50-75 (3 files)
HorizSync 28-50 VertRefresh 43-75 (3 files)
HorizSync 30-92 VertRefresh 50-85 (1 file)
HorizSync 28-38 VertRefresh 43-72 (1 file) - this is what Xorg / Dexconf set
I tried 28-50 / 43-75 and I now have 1024x768 @ 60 back. Thank you very much for your help! I just hope I'm not damaging my monitor with bad values.
