Are the Linaro optimizations helpful for the Xoom platform? I was under the impression the improvements were for ARM in general, but one of their engineers made a test bed specifically for the galaxy nexus, and that's what made it so easy to implement their code. Hence, the CM9 release of linaro for galaxy nexus (which I'm running now). I don't think, the way the code sits now, it would be as easy for the Xoom. Linaro might wanna release code specific to the Nvidia hardware... which may be never. I'm non developer and am not an expert, but I think those guys work on ARM as an embedded platform, not developed android ROMs for phones/tablets. It was more of a proof of concept.
