Sounds reasonable, or at least possible. I've been doing something
similar. If I remember correctly...

I defined 'devalias usb /pci@f2000000/usb@19/disk@1' and then booted
with 'boot usb:,\\:tbxi'. The idea was probably to be able to use the
same stick on several machines, as the OF path for the USB stick
varies. In any case, ofboot.b has to be patched to contain 'boot
usb:2,\install\yaboot'. Or, you could boot yaboot directly with this

My iMac G4/800 has USB 1.1, which makes the boot process quite slow.
