Say David don't worry my info is dated so your observation is fair. Do you know if the Matrox Mystique is supported with reasonable performance? Just got two laying around and it will be nice if they are supported because of the work that is going on with the Bt848 driver. With video cards which have a linear frame buffer and a pixel order of rgb we have no problems doing PCI to PCI transfer however there are cards such as the Millenium which I don't have one whose byte order is BGR or pretty close to that. One good thing that I can say about the Mystique is that the character display is razor sharp compare to the S3 cards.
