IBM HS21 Nic Problem

I've got some IBM HS21 ESX boxes initially with 2 nics, the bus is orderd is as follows

vmnic0 04:00.0

vmnic1 06:00.0

If it then add an extra 2 nics with esx pre-installed I get this

vmnic0 04:00.0

vmnic1 06:00.0

vmnic2 0c:04.0

vmnic3 0c:04.1

so far so good.

however if I rebuild the esx server with the 4 nics attached the bus order changes

vmnic0 0c:04.0

vmnic1 04:00.0

vmnic2 06:00.0

vmnic3 0c:04.1

I would have thought that the bus order should correspond to vmnic numbering, this is a real pain. I think it is the esx install that is enumarating the pci devices in the wrong order.

Does anyone know how to specify the vmnicx -> pci slot mapping during install (this is a scripted install)
