|    You would need updates to the sparc64 PCI back-end as well... but apprently,
|    this is also causing *problems* for some folks (sure wish I knew why it
|    failed for them but worked for me), and eduardo disabled part of the code
|    that you need for my changes to work.
|    
|    So, it's back to the drawing board.
