Can you try fbset -accel false and see if it helps? If it does, this is a problem with nvidia's imageblit function which converts big-endian bitmaps to little endian? Perhaps the help reverse_order() is not needed for your arch. Can you comment out calls to reverse_order() in drivers/video/nvidia/nv_accel.c? > Switching CONFIG_FB_NVIDIA off eliminates the problem.
