actually the m6 does support powerplay (and dynamicclocks), but
dynamicclocks is not the same as power play.  dynamicclocks just sets
up the varios GPU clocks in dynamic mode so they scale based on usage.
 powerplay involves much more.  ati has not released any information
about powerplay so it won't be supported anytime soon.
