The New World Roms support additional Open FirmWare drivers for booting
from USB AND FireWire, a byproduct of adding boot support for UDMA66

USB Storage Devices 3 The Macintosh USB software supports booting from an
external USB storage device. Class drivers are software components that
are able to communicate with many USB devices of a particular kind. If the
appropriate class driver is present, any number of compliant devices can
be plugged in and start working immediately without the need to install
additional software. The Mac OS for the iBook includes USB Mass Storage
Support 1.3, a class driver that supports devices that meet the USB Mass
Storage Class specification. See USB Drivers (page 70).

On the iBook, the Open Firmware code has been extended so that the device
tree describes the new hardware features of the computer. The Open
Firmware code also includes FCode drivers for the new hardware channels:
UltraDMA66, FireWire, and USB.

Imagine booting LinuxPPC via FireWire or USB on new Macs before you can
boot any *nix on other architectures. (Well... Ok, I suppose that the Mac
OS X Consumer Release might have it first.)
