I'd try to both use ForcePanel and PanelSize options.
You need to create an /etc/X11/xorg.conf file with only a device section :

Section "Device"
         Identifier  "Card0"
         Driver      "openchrome"
         Option      "ForcePanel"
         Option      "PanelSize" "800x480"
EndSection

I'm not sure such a partial xorg conf will work, but in case it's not 
just follow the doc in the link below to create a conf file and add the 
2 Option lines.

Also please provide your xorg log (and please compress it so it'll not 
hit the mailing list size limit).
