What version of the driver are you running?  mergedfb support was
deprecated during the 6.7.19x series in favor of xrandr 1.2 support.
If you are running driver version 6.7.19x or newer, toggling between
clone and dualhead is easy using the xrandr utility.  See this page
for more info:

The metamodes option is wrong.  You want something like this:
Option          "Metamodes" "1680x1050-1680x1050 1680-1050"
