 I am working on tests, and i have discovered some issues with my current implementation.
 Whether i concentrate my efforts on fixing them or just redo everything from scratch, depends on
what you say no. So what is the final verdict? Should we:
a) Change the default to PCI, for better performance; or:
b) Leave the default as it is, but make explicit <address type='pci'> working?
