I grabbed my stack of Motorola manuals.  All of the 6xx/7xx/8xx manuals
have a UISA section that describes the behavior of all implementation
dependent instructions.  The lwarx/stwcx behavior is clearly defined,
along with either 16 or 32 word granularity.......I have Gabriel's
patch floating around on a couple of systems for testing.  If you
try it, let me know the results please.

Thanks.
