Hi,
If you can confirm that there are no further tftp request after
downloading the yaboot binary,
Here is the version of yaboot from
Redhat, you can try it.
Some months ago, I found that the Yaboot package in Debian repository
can not boot from network, but the yaboot in RHEL 6.5 (ppc64) can.
Although it is from a 64bit server OS, but yaboot is always a 32 bit
elf, so I think it may also work under iBook.
