Yep. asus k8v-x with athlon 64 3000+.
No xruns after disabling the ethernet interface. Kernel is the one
shipped in Suse. I think it is fair to compile just the realtime module
with the patch applied to source. I still have the capability module but
don't load it.
With the nvidia driver some xruns appear at -p64 -n4 but just in some
critical occasions.
