Oh, that's a completly other aspect :-)

MagiC's interface is ok but it's dedicated to original ATARI's only. It's 
a wrong decision that the kernel wait for the interrupt. This 
informations and the interrupt handler must be private for the driver to 
abstract this for the kernel in a general way.
