[plug] screen resolution resolved

[William Kenworthy]

if you have xrandr 2, it might give you the control needed.  xrandr 1 is
fairly brain dead.  Try adding "IGNOREEDID" "1" and "IGNOREDDC" "1" to
xorg.conf if it supports it.  My laptop with a FC7 vm is at work so I
cant get a peek at the standard xorg.conf to see if the above is valid -
but give it a go ...

Check "man org.conf" and "man <xorgdrivername>" to get the correct
options.  You dont mention the video driver - wouldn't be an i810
variant would it :)
