From a community aspect is anyone actually going to use this?  Is this going to be the equivalent of voyager on x86?  I've got nothing against some of the endian clean ups this introduces.  However the changes to misc_32.S are a bit ugly from a readability point of view.  Just seems like this is likely to bit-rot pretty quickly.
