The cpu intake & exhaust are the same, they are handled by groups of 3 ie, cpu0_* is the 3 fans on CPU 0, cpu1_* is the 3 fans on CPU 1. Backside fan is supposed to blow on the U3 chip, I don't remember where it's located, and slots fan is the PCI one afaik.

OF netboot is limited to 4M sized zImages which can be a bit tough nowadays, but modern yaboot can netboot larger files.
