19 *
20 * Note that we now use the new fbcon fix, var and cmap scheme. We do
21 * still have to check which console is the currently displayed one
22 * however, especially for the colourmap stuff.
23 *
24 * We also use the new hotplug PCI subsystem. I'm not sure if there
25 * are any such cards, but I'm erring on the side of caution. We don't
26 * want to go pop just because someone does have one.
27 *
28 * Note that this doesn't work fully in the case of multiple CyberPro
29 * cards with grabbers. We currently can only attach to the first
30 * CyberPro card found.
31 *
32 * When we're in truecolour mode, we power down the LUT RAM as a power
33 * saving feature. Also, when we enter any of the powersaving modes
34 * (except soft blanking) we power down the RAMDACs. This saves about
35 * 1W, which is roughly 8% of the power consumption of a NetWinder
36 * (which, incidentally, is about the same saving as a 2.5in hard disk
37 * entering standby mode.)
