IIRC the problem with the ciregs happened when doing network loading in
yaboot. Yaboot is using the client interface as a "normal" client
already, but when it tries to load additional files like the kernel
image via TFTP, SLOF internally starts the net-snk as a second client.
So there were suddenly two clients using the Open Firmware client
interface at the same time. So the obp-tftp code had to save the ciregs
from yaboot before jumping into the net-snk client.
