Xorg.0.log of randr 1.2 initialization

I have a compaq (R3000) laptop with a 
"01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go
64M] (rev a3)"

I have an external monitor connected via the VGA port.  The external LCD
monitor is detected by the xserver, and I am able to flip modes with xrandr -s
0. 

The built-in panel on the laptop is simply blank.  The strange thing is that
if I disable 'randr1.2', it works just fine. 


(BTW. randr shows me all of the modes available for BOTH the external and
internal display, so it is doing the detection properly.)

BTW2. It is correct... The panel can handle 1680x1050..

[clmesarita at localhost media]$ env DISPLAY=:0 xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1680 x 1680
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 304mm x

   800x600        60.3  
   640x480        59.9  
....

I don't mind hacking around with this... Where is a good place to start?
