0010 Many laptops released in 2008/9/10 have two GPUs with a multiplexer
0011 to switch between them. This adds support for dynamic switching when
0012 X isn't running and delayed switching until the next logoff. This
0013 feature is called hybrid graphics, ATI PowerXpress, and Nvidia
0014 HybridPower.
