Hi, I use the nouveau driver on archlinux since aprox. 1 year with a 7xxx 
card. The soundcard is the legendary maudio 1010l. I never had problems with 
xruns since I'm using nouveau. If you have specific tests to run on that 
system, I can perform them on the machine in a week or so (as soon as I'll be 
back from my holidays).

Best, Bjoern
