[kde-linux] X configuration/Xorg 6.9

I have a Thinkpad T40 (2373) with a Radeon M7 video card.  It is connected to 
a Sony X93 external LCD monitor.

With Mandrake 9.2, 10.0, and 10.1 running XFree and more recently XOrg through 
verson 6.8, the XF86Config file shown below allowed me to work with a single 
virtual desktop spanning the internal and external LCDs (Xinerama).

I recently upgraded to Mandriva 2006 which uses XOrg 6.9.  The virtual desktop 
remains, but no signal is sent to the external monitor and as a result I can 
only see the left portion of the virtual desktop.  The problem isn't fixed by 
cycling through the internal/external/both monitor signal (Fn+F7) setting.

Can anyone explain why the change in behavior and suggest a way to fix?
TIA
Paul
