Yup, this looks like the correct fix to me.  I came out to the same
result when I merged.  I've also build tested for booke.

Linus, I've done a trial merge and pushed it out to the next-resolved
branch on my tree (pull req below).  You can either use my previous
pull request and fix it up yourself or use this one:
