K4 Working around a broken screen?

Hi everyone.

I have a Kindle 4 NT, and unfortunately there is a small chunk of the screen that no longer refreshes.

Here is a pic:


Its not as bad as it could be, but it still obscures the progress bar. I tried changing the resolution the framebuffer outputs with fbset, but it seemed to have no effect. I also tried librerator, but unfortunately, there didn't seem to be a way to push all of the content up a few pixels, so some of the text was obscured.

Is there any way that I can make it so the content on the screen gets pushed up a few pixels?

Thanks in advance!
