Like a protest?
I think our equivalent of the Hungarian-flag-with-the-coat-of-arms-cut-out would be the Eureka stockade flag:

It is often used here as a general symbol of freedom and nationalism. Is the flag-with-a-hole used like that in Hungary or is it only really associated with the revolution?
