Happily, life is much simpler on 32-bit sparc systems. The "intr" property, preferred over the "interrupts" property is used-as. Some minor translations of this value happen on sun4d systems. The stage is now set to rewrite the sparc serial driver probing to use the of_driver framework, and then to convert all SBUS, EBUS, and ISA drivers in-kind so that we can nuke all those special bus frameworks.
