+ * Integraphics CyberPro 2000, 2010 and 5000 frame buffer device
+ *
+ * Based on cyberfb.c.
+ *
+ * Note that we now use the new fbcon fix, var and cmap scheme.  We do
+ * still have to check which console is the currently displayed one
+ * however, especially for the colourmap stuff.
+ *
+ * We also use the new hotplug PCI subsystem.  I'm not sure if there
+ * are any such cards, but I'm erring on the side of caution.  We don't
+ * want to go pop just because someone does have one.
+ *
+ * Note that this doesn't work fully in the case of multiple CyberPro
+ * cards with grabbers.  We currently can only attach to the first
+ * CyberPro card found.
+ *
+ * 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.)
