All PCI and PCIe cards use PCI enumeration, where the card 
can be forced to respond by slot during enumeration, and a 
block of ROM data giving a text string, Vendor ID and device 
ID and a description of features including register layout.  
The PCI enumeration then figures out a good fit in the I/O 
address space and assigns addresses to the card.

So, even if you leave a card in the same slot but add 
another card, these addresses can get changed.
