My notebook going to get hot when i booted to linux, and get cold when i boot to OS X.

There is experimental support for powerplay on the agd-powerplay branch of my ati repo on fdo:
http://cgit.freedesktop.org/~agd5f/xf86-video-ati/log/?h=agd-powerplay

Unfortunately, the power mode is statically defined at start up.  We need randr GPU objects in order to allow the user to change this dynamically.
