Here are two suggestions:
1) boot enough of MacOS on your iMac DV in order to
run the LinuxPPC live installer, and do your work from
there instead of on the pee-sea
2) export your iMac's root filesystem via NFS from
your pee-sea
You sound very intrepid so far :) Congratulations
on your current status and I hope you get more
progress.
