Thanks for the description. If possible, a picture might also be useful.

Should be possible via metamodes. Looks like the syntax you have
currently is not quite correct for this though.
Also, it looks like MergedFB is limiting the virtual resolution to the
external display's maximum resolution; does it make a difference if you
specify
Virtual 1280 854
in SubSection "Display"?

Probably not.

Does
Option "ColorTiling" "off"
make a difference?

Do different values for this and Option "IgnoreEDID" make a difference?

The radeon driver doesn't support two digital outputs at the same time
yet. You'll have to connect the external display via a DVI->VGA adaptor
and use Option "MonitorLayout" "LVDS,CRT".

Does enabling this make a difference?

This option is basically useless and might even be harmful.
