I have made some progress, but still not perfect.  Please see the 
updated configuration:

Now I have messages from 3 Radeon(x) devices ... The error log above is 
produced by the "Triple" layout. (doesn't work, but contains good info)  
The "Single" isn't working either.  I have even tried replacing 
"Screen1" with "Screen2" or "Screen3"... neither work in "Single" layout.

The "Double" Layout DOES work, except I can only see a picture on the 
primary monitor.  X seems to think that there is a second monitor 
functioning, as the mouse moves off the screen, but I dont see a picture 
on either of the other two screens.  This is working with it setup to 
use the 2 screens hooked up to 9600XT (screen1 and screen2).  I've tried 
using Screen1+Screen3 and it doesnt work.  Same as Screen2+Screen3.

errors like this jump out at me:

So, on the bright side, now I don't have to disable surroundview in BIOS 
in order to get X working.  I'd like to get dual and triple monitors 
working.  Any more suggestions?

Thanks,
