That's not really what this commit is about - it's about making the
code consistent with the comments in the file. I could have instead
changed the comment saying "4x" to "3x" instead.
There isn't really an answer which will always work for this problem,
as I've already detailed in a previous thread discussing the issue.
Adding a zImage header don't fix the problem.
