This is simple preview how to fix output on N900 display:
diff --git a/drivers/video/cfb_console.c b/drivers/video/cfb_console.c

But I think that function video_invertchar which is needed for rendering cursor
should be fixed properly.
Can somebody check if current implementaion of function video_invertchar is
correct? I do not properly understand that code, so I cannot debug it.
