[xf86-video-intel] Need help solving issue with intel driver & DDC monitor detection

Ok now that I have virtual size "3360 1200" DVI is behaving diffrent
behavior. Lets just say there is definitely a bug.
Issue
====
So it appears that DVI has some strange issues with my Samsung 243T.
Connected on X Startup
-----------------------------------
Over DVI the monitor will start with resolution 1280x1024. When I try
to send any xrandr commands they are ignored. Using "xrandr --output
TDMS-1 --right-of LVDS --auto". The monitor does nothing. I can't get
it to change the resolution either.
Hot plugged
-----------------
When I hot plug over DVI xrandr shows the correct values for my
monitor. But when I use the command "xrandr --output TDMS-1 --right-of
LVDS --auto" .. nothing comes to the screen!
I've seen others report this on the mailing list, but they where using
hdmi port.
Observations
===========
* In my last email I mentioned that I tested with a samsung
(1650x1050) monitor, well that was not with my Thinkpad T61 but
someone elses 15" Thinkpad T61 that had an LVDS of the 1650x1050.
* Could the problem be that if the DVI monitor has a higher resolution
then the LVDS then this is causing an issue (the data would seem to
show that). When I moved around the init code in i830_driver.c and
placed the dvi (svdo) init code above lvds init code it had worked on
startup.
Here is some xrandr data. I first give xrandr data from a working
machine (my Thinkpad T41p) , then show for the diffrent cases on
Thinkpad T61 with the x3100 over DVI.
