* When we're in truecolour mode, we power down the LUT RAM as a power
* saving feature. Also, when we enter any of the powersaving modes
* (except soft blanking) we power down the RAMDACs. This saves about
* 1W, which is roughly 8% of the power consumption of a NetWinder
* (which, incidentally, is about the same saving as a 2.5in hard disk
* entering standby mode.)
