It looks like the call to execve() at the end of start_init() in
init_main.c is screwed:

                if ((error = execve(p, &args, retval)) == 0)
                        return;
                      
Replacing p with arg0 gets the kernel a little bit further, but quickly
crashes.  Could someone more familiar with what start_init() is
supposed to be doing take a look at this?
