This driver supports Sun CG12 / Matrox SG3 graphics boards.
The card ( if you can call it a card - in fact it's two cards on top of each other which occupy three ?SBus slots ) supports 1, 8, 12 and 24 bit visuals with 2D and 3D acceleration ( which we don't know how to use, yet ), the console runs in 1 bit monochrome since that's what the firmware sets up, ?Xorg with the ?wsfb driver will run in 24 bit colour.
