That would be me :) I thought I said _something_ about the patch, but
then again I miss them on occasion. 

The question I have is whether or not it would be best just to turn off
branch-likely for the sibyte chip in the sources? However, I can see a
reason for the patch anyhow so if Mike would like to check it in then
that's fine.
