I am also sure that it is not the case (nouveau). 

I installed opensuse11.4 as a last trial. 

But I've got same error with the trial before (centos 5.5, xen provided by 

Let me elaborate little bit. 

 1. nvidia-smi works fine
 2. devicequery also works fine.
 3. except devicequery, all applications fail. Error message is same "
