Okay, thanks Sinan. I ~think~ we're on the same page here. Our guy Michael Werner is carefully going through our drivers with Steve Wise. I'd like to let them work on the changes with a lot of thought and testing before diving in too far. We had thought that we could get around the lack of a real Relaxed Ordering Write on the PowerPC via the __raw_write*() API, but that isn't really part of the defined API and various platforms define that API differently (some doing PCI Byte Ordering rearrangements and some not). I think that we're going to have to work with the PowerPC platform folks to get a real Relaxed Ordering Write.
