I'm not sure why you don't think you need a GPU driver installed.  When the
driver is installed it not only allows the GPU to dynamically adjust it clocks
and voltages up for performance, but also enables low power states and turns
off certain blocks when they are not in use, so overall, you'll probably save
more power with the GPU driver loaded than just leaving the GPU in the state
set up by the bios.
