David already told me he didn't have time to maintain fixes for 2.6.32,
which I can understand considering the number of stable branches now.
However I usually backport fixes from 3.0 so in general I have all the
required fixes. I don't have this fix in my queue right now, so I'm
adding it now.

Thanks for letting me know!
