And I thougt my idea to use an approach similar to the Dallas stealth clock 
chips is warped ;)

These chips use magic read patterns to write to the clock chip, that is 
installed in a ROM socket. In the same way, a flash chip could be 
programmed, but of course you had to build a stealth controller on your own 
to interface between the flash chip and the ROM socket ...
