[PlanetCCRMA] Unthreading devices?

[Rick B]

Hi all,
    I'm still using the 2.6.8.1-1.520.1vR9.ll.rhfc2.ccrma kernel, and 
have my video card unthreaded. My question is: does an app have to be 
specifically designed to take advantage of unthreaded devices? Or is it 
as simple as unthreading the device by doing a "echo 0 > 
/proc/irq/10/nvidia/threaded"? I want to make sure my video card gets 
first preferece on the pci bus to avoid dropouts.
