If SerialICE is relocatable to have all code in CAR and if it can do batched commands (<start_transaction>, <bunch_of_memory_writes>, <end_transaction_and_execute_now>), it is reasonably easy to have flashrom rewrite the ROM over the SerialICE interface. IMHO that's a pretty good way to recover from a non-booting machine because it only needs a serial line (or whatever you're using to communicate with SerialICE).
