Not mentioned here, only in the code:

* index defaults to 0 for the first device to initialize, 1 for the
  second, and so forth.

* It is okay to overwrite the defaults provided by index, e.g.

    -device isa-serial,index=1,irq=4

Looks fine to me.  A similar solution could do for default mac address.
