I deliberately left the pci stuff out of my submission to keep things 
simple and because I have no way of testing it. Eventually we (allied 
telesis) are planning a product variant that will need a 2nd switch 
connected via pci so I'll be revisiting the pci stuff then (unless 
someone else beats me to it).
