qemu needs to export these two bits of information: the first free slot 
and the number of slots.

More generally, which slots are open.  We can assume 1:31, but that's 
unlovely.

Paul/Anthony, can we have -vga pci_addr=, -usb-controller pci_addr=, and 
-drive pci_addr= (and later, -disk-controller)?  Stalling while waiting 
for the ultimate config file is only generating pain and out-of-tree 
patches.

(I'd be quite happy constructing the entire machine config on the 
command line, but I realize it's just me)
