dual-DPU XRandR almost working, DVI-0 stays blank (was: "Screen 1 deleted because of no matching section")

You'll have to Zaphod the head. Good luck. :3

A reboot of the machine fixed that.

Now it seems like the only remaining problem now is that Screen 1,
which is the Radeon 9200 card, provides a display spanning both
monitors, but it appears to my window manager (awesome) as a single
head.

xorg.conf and log attached.

xrandr again shows everything as I'd expect it, but something is
preventing X from creating two heads for the screen:

 % xrandr -display :0.1 -q                                   #1,10022

Screen 1: minimum 320 x 200, current 2560 x 1024, maximum 4096 x 4096
DVI-1 connected 1280x1024+...
How can I split the screen into two heads? Note that I do not want
to return to pure-Zaphod and duplicating Device/Screen sections for
each of the two ports of the Radeon 9200 (using Screen 0/1 lines),
because I'd just run into the problem described here again:

the early bird may get the worm,
