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 > > The second patch enables new functionality.
