Ati actually wrote most of the code.  The databooks I have don't have
much on the powerplay stuff.  ati may be willing to provide docs or
code, unfortunately, much of it may rely on kernel based power
management, and since the current driver is userspace, it' can't be
supported ATM.  this may change with the whole big graphics on linux
re-work thats starting to happen.
