problems with "ATI proprietary" R500 driver on xorg server 7.0.1

[Dan Engholm]

Dear list,

I have a PC with an ATI FireGL V3400 display adapter.  It has two flat 
panel LCD monitors connected via DVI and I want to set it up with a 
single desktop spanning the two.  After some research, I figured that I 
had to install the ATI proprietary driver to get the Xinerama extension 
for this card so I got it and installed it with no apparent problems.  
Unfortunately, aticonfig reports that it cannot find suitable hardware 
so I had to configure the server by hand.  I found that it works just 
fine with Clone on and Xinerama off but if I reverse the two, the server 
crashes with this in the log:

Backtrace:
0: X(xf86SigHandler+0x71) [0x48e8f1]
1: /lib64/libc.so.6 [0x3b2b6302d0]
2: X(xf86RandR12CreateScreenResources+0x38e) [0x4b7c0e]
3: X [0x4b1d3f]
4: X(main+0x2e5) [0x4333b5]
5: /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b2b61d994]
6: X(FontFileCompleteXLFD+0x229) [0x4327f9]

The driver says this of the adapter:
(--) R500(0): Chipset: "ATI FireGL V3400" (ChipID = 0x71d2)

I could not find any driver version information in the log but I just 
downloaded it from AMD on the 15th.  The installer's filename is 
ati-driver-installer-9-9-x86.x86_64.run.

If anybody has any ideas on how to get around this problem, I would 
appreciate hearing them.  Other information is available upon request.  
Thanks in advance.
