The only effect is the slot numbering of the devices in your domU
("resorting the devices" as you call it). Virtual PCI renumbers
everything to bus 0 while passthrough mode leaves them at their real
slot numbers. Passthrough *may* be required for certain device drivers
which look for devices at certain slot locations (but I've not seen this
in practice).
