Sorry I don't have easy access to any hardware that fits the bill. At
some point I'll be able to go to the office and setup a machine that (I
think) can test these paths, but I don't have an ETA on that.

You and others seem to have done lots of analysis on this though, so I
think you should merge the fixes without waiting on ppc32 testing.

cheers
