In order for your system to boot after having bfu'ed these bits, you
must manually remove the lo driver from your system. Otherwise, you are
likely to hit the following ASSERT() failure during boot:
panic[cpu0]/thread=cf22dde0: assertion failed: ns_reg[moduleid].nr_create == 0,

The reason for this failure is that the ipnet module is using a netstack
id that was previously the netstack id of the lo module, so both modules
have the same netstack id. Because all modules are loaded during boot
on a debug kernel, when the second module loads, netstack_register()
thinks that it has already registered and panics.
