Oh... I didn't test with Gnome or KDE, as I'm using Awesome (which works fine). Maybe if you deactivate composing it will be better (as a temporary solution)?
I'm working on improving the patch: at the moment, it turns some bits on (enabling some features?), but the blob also writes some things (feature configuration?) before turning each bit on. So maybe finding what those things are and implementing them will fix the errors.

I have seen it once or twice too, but not at each boot.
On a similar note, I sometime get PDISP errors about an unknown method when loading Nouveau, but as it rarely happen, I haven't tried to fix it yet. I'll have a look at both errors later on.

Thanks for testing! :)
