This regression does still need to be listed for 2.6.33-rc8-git.

Americo is right that the warning goes away if I apply those patches from Eric,
but they look like more than we'd be adding into 2.6.33 at this stage ...
and bootup of latest git plus those patches gave me 71 messages of the form
BUG: key fxxxxxxx not in .data!
