ATI Radeon 7500 dualhed - monitors on same viewport?


I have had an ATI Radeon 7500 around for quite a while, and I used to use it under Linux in a MergedFB expanded-desktop configuration quite successully. I recently installed OpenSuSe 10, and manually set the necessary Xorg.conf directives to set up a dualhead configuration with the secondary display to the right of the primary. Now both displays turn on, but apparently in "clone" mode (both showing the same area)... There is, in fact, a virtual desktop area beyond what they "see"; I can move the mouse cursor off the right edge of the screen, and the KDE Desktop Pager shows a big wide desktop area. I have been fooling around with this all day, to no avail. Both displays are acting as the primary! I'm using the same motherboard and video card I had been using back when I had it working perfectly, so perhaps this is a bug in X or the "radeon" driver module? I also tried the "ati" driver, with identical results...

Below is my current xorg.conf file.

Hooray!

Problem "fixed" by drastic forced upgrade to package set from OpenSuSe 10.2 Alpha... of course, it broke the rest of the system, but hey! Now the dualhead setup works.
Now I have to figure out why trying to log in through KDM as any user except for root causes X to crash and restart... :-D
