[Intel-gfx] xrandr doesn't show modes that EDID finds

[dolphinling]

I have a computer with an 845 graphics chipset and a sun monitor (don't know the 
exact monitor model, can get it if necessary). xrandr does not show many of the 
modes that the monitor supports (most notably, anything over 1280x1024)

The monitor is a 21 inch CRT with two inputs: input 1 is a 13W3 connector, and 
input 2 is a vga connector. Input 2 is the one in use.

The kernel is a current git drm-intel-next, with KMS. The X server is 1.6.2, 
xf86-video-intel is current git, and xrandr, libXrandr, and randrproto are all 
version 1.3.0.


The following shows in Xorg.0.log:
