This second chunk fails miserably.  I don't know what you diffed it
against, as it doesn't look like anything that I currently have in that
function...

Anyway, can you grab the next -mm release and rediff this patch against
the bk-driver-2.6 tree, or even against a clean 2.6.6 tree so that I can
apply it?
