Still a few doubts about Zaphod and Radeon

[Lawrence Statton]

I feel that I have arrived at a fortuitous time in that Zaphod is 
(apparently) back

I'm a greybeard and I *like* each of my monitors to have it's own X 
screen (:0.0, :0.1 and :0.2) for reasons that probably make sense to 
nobody but me.

I have a IBM ThinkCentre with Intel 915 graphics on the motherboard and 
a Radeon 9000 series dual VGA PCI card.  The motherboard video is 
driving a 22" HP LCD and the Radeon is driving a pair of HP 17" 4:3 LCDs.

After a side trip into "my window manager sucks" land, and me blaming 
the good folks over at GDM for compiz (and more importantly my own) 
lossage, I now have all three displays with distinct video in a "usable 
but not quite perfect" configuration.

I'm up to two X screens, :0.0 ( the IGP video)  and the radeon card 
driving a virtual 2560x1024 frame buffer driving the other two monitors.

I saw Alex Deuchar's recent response on the list to Samud and I 
immediately tried to duplicate (as close as possible) their results, but 
without luck.

Alex writes:  "You need to add Screen 0 and Screen 1 to your device 
sections"

Is this correct?  When I tried to do this, I got a coredump
