 From your conf :

Section "Device"
	Identifier "CX700"
	BoardName  "Unichrome(CX700M2)"
	VendorName "VIA"
	Driver	   "openchrome"
	BusID	   "PCI:1:0:0"
         Screen     0
	Option     "VBEModes"            "true"
	Option	   "ActiveDevice"     	 "CRT"  	  # LCD or CRT
         Option     "DisableIRQ"
	Option     "EnableAGPDMA"        "true"
	Option     "SWcursor"            "true"
EndSection

Section "Monitor"
	Identifier         "Xenarc-700TSV"
	Option             "DPMS"  "true"
	HorizSync          31.50-37.90	
	VertRefresh	   50.00-70.00
EndSection


For the Device section :
BusID is unneeded unless you have several cards.
VBEModes makes the driver uses VGA bios to do the mode setting and it's 
unneeded for VGA on a CX700. It's even probably counter-productive.
DisableIRQ is probably unneeded, unless you have have some missed IRQ. 
This is only the case on K8M800 and some KM400.
Using AGPDMA is the default on CX700, so no need for EnableAGPDMA.
SWCursor is unneeded unless you have issues with hardware cursor.

For the Monitor section :
Your monitor is probably advertising its HorizSync and VertRefresh (as 
well as the modelines for the modes it supports) over DDC. Remove those 
options unless your monitor doesn't do that, which is unlikely on recent 
hardware, or you have trouble with the given values.
