You're right, there is no firmware that capable to find PReP on GPT
(even UUID is not registered. Yet?). But we still can boot from 0x41
and later on scan GPT partitions.  So 0x41 is in pMBR (or
gpt_sync_mbr) The root shouldn't be there, so we don't have 2TB limits
for root devices.

I've tested that under KVM. With PReP in msdos and root with ext3 fs
on GPT (mbr doesn't have it). So I placed just dummy yaboot.conf under
/etc/yaboot.conf.
