How about making isa-bus.c own the i8259 array then?  We could pass it 
to isa_bus_new.  Then switch over to reference isa irqs by number.  That 
allows isa-bus to keep track of the allocations.  Maybe it makes sense 
to kill the sysbus-style isa_{init,connect}_irq split and have a irq bus 
property then.

cheers,
   Gerd
