Not sure what you mean by this. If there are versions of nouveau 'in the wild' (widely used by non-technical users) that result in brokenness under some circumstances-- and bugfixes in the driver are not promptly available, it makes sense to prevent use of the hardware driver i.e. "blacklist" it. So, are you saying that using nouveau does not result in broken behavior, and that any such brokenness is quickly fixed?
