Enable the debug UART and emit a single 'a' early in the init sequence to show that it is working. Unfortunately the debug UART implementation needs a stack to work. I cannot seem to remove this limitation as the absolute 'jmp %eax' instruction goes off into the weeds. So this means that the character output cannot be any earlier than car_init_ret, where memory is available for a stack.
