Indeed, it works fine 8-)

I did not know that __attribute__ ((interrupt)) was available on m68k. 
It seems that __attribute__ ((interrupt_handler)) is a synonym.
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html#index-interrupt-handler-functions-2591

In both cases, GCC backups all the registers (including d0/d1/a0/a1) and 
returns using rte (instead of rts).
