The driver does it's internal device detection using Open Firmware. Take a look at this in the kernel source: arch/ppc/kernel/prom.c It's sort of like a PCI device table, except it includes all sorts of hardware interfaces besides just PCI devices. If you have a newer Mac around (made within the last few years), you can hold down option-o-f while booting to get into the Open Firmware 'shell'. It's a Forth type interpreter which lets you do various things like browse the hardware of the computer or change some boot params.
