I think we can push this bug upstream with the current information.
Could you take a look at this proposed bug report for upstream and see
if it looks all right? (the architecture is missing, do you have 32-bit
or 64-bit?)

Title: [i945GM] EDID information of monitor on VGA not detected

Forwarding a bug from a ubuntu user:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/376722

Bug description:
With a LCD LG TV 19LS4D connected to the VGA port on a Sony VAIO vgn-sz1m, the EDID information is not detected. The EDID information is detected with the 2.4 version of the driver, but not with 2.6.3 and above (also tested with 2.7.99). This results in the native resolution of the external monitor (1440x900) not being available. The maximum is 1360x768.

Since the internal LVDS has a native resolution of 1200x800, he needs to add 
	SubSection "Display"
		Virtual	1680 1200
	EndSubSection
to the "Screen" section of xorg.conf in order to get the higher resolution even with the 2.4 driver.
