I think this is your problem:

    Option  "VBEModes" "true"

As I understand it, this means that the driver will only use pre-set
modes, and will ignore your mode lines. Unfortunately, removing it will
stop the driver working at all.


If you look at your xorg.log you'll see lines like this (surrounded by
line noise):

    *Mode: 168 (1920x1080)

I *think* these are the only ones supported 'natively' by the CX700M2.


I'm hoping that this is just a temporary thing while the developers get
more of the chip features implemented.


I've spent much of the last week trying to get the component-out working
at HDTV (at least 1280x720) resolutions, but at best, I get a 3cm black
border on my TV, at worst, tiled screens. I'm hoping that the DVI-HDMI
cable I'm borrowing tomorrow will work out...
