G45 graphics chip resolutions - maximum 1280x1024, surely not!

[Chris G]

I'm running 8.10 beta on an Asus P5Q-VM motherboard which has the
Intel G45 graphics hardware.

When I run ddcprobe it reports the following for the graphics
hardware:- 

    vbe: VESA 3.0 detected.
    oem: Intel(r)Eaglelake Graphics Chip Accelerated VGA BIOS
    vendor: Intel Corporation
    product: Intel(r)Eaglelake Graphics Controller Hardware Version 0.0
    memory: 131008kb
    mode: 1280x1024x256
    mode: 1280x1024x64k
    mode: 1280x1024x16m
    mode: 1024x768x256
    mode: 1024x768x64k
    mode: 1024x768x16m
    mode: 640x480x16m
    mode: 800x600x64k
    mode: 800x600x16m
    mode: 640x480x256
    mode: 800x600x256
    mode: 640x480x64k


Surely the hardware can do better than that!   Is there anything I'm
missing in getting it to tell me about higher resolutions?
