Please try the attached patch I'm hoping it will enable interrupts properly.

I'm unable to test it as my powerbook is my only NetBSD capable mac.

It also includes the addition of an audio device to conf/majors.mac68k

So please make the appropriate device nodes and hopefully you will have a 
fully functioning audio device.

mknod audio0 c 56 128
mknod sound0 c 56 0
mknod mixer0 c 56 16

Best regards,

Nat
