2.6.38.2-10 + nouveau

Generally had no issues with this kernel except for this one: I notice when I logout there are dropped random "bites" of little sets of pixels which appear .. perhaps 10-30 of them .. these are small black squares against the blue background. Nouveau driver (on f14 fully updated). I see that there is a patch in the -11 kernel on koji - I'll try that and see if it goes away. gene/
