It was too good to be true, a simple two-liner would solve this, heh. I think I know what to do (needs testing, will be tomorrow at earliest); but deeper investigation shows we use rs6000_cpu in quite a few places where we mean rs6000_tune (which doesn't exist). I don't know how deep this pit is. Feel free to revert my patch (if it takes too long to fix this, I'll revert it myself). Sorry :-/ Segher
