So I've managed to be able to get into 1440x900 mode by hand by running
xrandr --output VGA0 --mode 1440x900
However the screen occasionally does a really vicious redraw where it
flickers to gray as it redraws, it's pretty distracting.
I've created a gist of the xorg log output, perhaps someone can see
something here?
