I have an idea what that is actually and I've seen similar on Fedora I
think

Can you do the following. In gma500/framebuffer.c find the code that
reads

        info->flags = FBINFO_DEFAULT;
        if (dev_priv->ops->accel_2d && pitch_lines > 8) /* 2D engine */
                info->fbops = &psbfb_ops;
        else if (gtt_roll) {    /* GTT rolling seems best */
                info->fbops = &psbfb_roll_ops;
                info->flags |= FBINFO_HWACCEL_YPAN;
        } else  /* Software */
                info->fbops = &psbfb_unaccel_ops;

and change it to read


        info->flags = FBINFO_DEFAULT;
	info->fbops = &psbfb_unaccel_ops;

and see if that fixes it.

If so I know what is going on.
