one problem:
don't use metamodes in the display section of your screen config:

    Subsection "Display"
        Depth 24
        Modes "1400x1050-1024x768" "1024x768-1024x768" "1400x1050" "1024x768"
    EndSubsection

this should be:
    Subsection "Display"
        Depth 24
        Modes "1400x1050" "1024x768"
    EndSubsection

your the hsync you specified is probably too limited to display the
1400x1050 mode.  Plus what is the native resolution of your panel?  If
it's only 1024x768, you won't be able to do a 1400x1050 clone mode
since only your LCD can display it.  You'd need a mixed mode clone
mode. try adding 1400x1050+1024x768 as a metamode (the '+' option may
only be in cvs HEAD).

the clone modes don't shut off the enternal monitor, you can just use
them with xrandr to resize your desktop deom dualhead to single head. 
there's no way to dynamically control outputs in xorg at the moment.

Rotation isnt supported by the xorg radeon driver.
