If you are still running X with enabled DRI, then it is known problem. When DRI is enabled in X, mga driver randomly reprograms some Matrox acceleration registers (color depth, screen width, byte ordering) - so you must use same depth and resolution in both X and on console if you are using DRI. I believe that it is problem which thunder7 sees. I never got reported that matroxfb just decided itself in the middle of screen to do something else, it was always tracked to X running on (invisible) background, but still playing with accelerator.

P.S.: You can try 'fbset -accel false', but fixing X is better.
