Well I think it supports only ieee1275 machines, aka those with
openfirmware.

Well at least my understanding is that the newworld machines, the IBM
cell machines, and the IBM power machines should all be openfirmware,
and hence should work with grub.

Do oldworld still use QUIK?

I saw in centos's documentation that for IBM i and p series they say
the PReP boot partition should be 4 to 8MB and never over 10MB.
The HFS boot size changes certainly sound sensible.
