I'll fix it. Give me a few hours.
It boots fine on rs6000 for me, and passes regression tests, but if
it's failing on x86, it means store_motion isn't being conservative
enough. (I have a good idea where this is, i wasn't sure about one
piece of code).  For the moment, commenting out the call to
store_motion should be a temporary fix.
