My reading of your xorg log makes me think you're using precisely the 
mode it's asking for itself:

These are the same. And having just had a quick look at the VESA 
spreadsheet - http://www.vesa.org/Public/CVT/CVTd6r1.xls - this is a 
perfectly standard VESA CVT mode with reduced blanking, so it ought to 
be absolutely perfect.

Try using your own modeline - perhaps Jelle's one, or the one from that 
web page you mentioned - and call it something other than 1680x1050 e.g. 
My1680x1050 so it doesn't get confused with the one the monitor's asking 
for.

I'm also wondering if something in openchrome or X doesn't like reduced 
blanking; I think it may have come up before.

Cheers,

John.
