QSB power

Does anyone have experience getting the power consumption of the QSB down?

Our application does not need any of the audio or video functionality.

At the LINUX prompt the board draws 380 to 500 mA from the 5V main supply. Thats about 2W to 2.5W.

The Freescale app note says that LINUX can draw about 160 mW while playing an MP3 file from SD,

Is there some low power demo code I can run and/or does anyone have experiene reducing the power consumption of the QSB?

Thanks.
