Maybe if they all take the same driver they are probed in a fixed order. 
  Mine usually have a mix of at least broadcomm and intel. Also note 
that once the NIC mac address is set as HWADDR= in the ifcfg-eth? file 
the settings will stay fixed (with a weird scheme of renaming the device 
after kernel detection...).

Clonezilla just copies your source, so the same thing happens as would 
happen if you moved the original disk to a different chassis - which is 
also a likely scenario for me.  Kudzu will rename your ifcfg-eth? files 
with a .bak extension and create new ones that default to dhcp.  If 
kudzu doesn't run and you have the wrong HWADDR= setting in the file the 
interface won't come up at all.

This gets a lot harder when you've shipped the disk elsewhere for 
installation and the operators there only know windows.

I think the bsd's have a mapping between the driver needed and the 
device name.  I don't really care what the name is, as long as I know 
the names that correspond to the physical jacks and they are consistent 
across machines with the same bus/card layout.
