HowTo: Install freebsd-ppc on a g4 mac mini?

[Cypher Frost]

Has anyone written a detailed how-to for installing the PPC port of FreeBSD
onto a g4 mac mini as the only OS?

I want to use a mini to replace my current BSD server due to it's small
size. However, I've been finding issues regarding the OpenFirmware that
boots the mac. I've seen that it only reads HFS+ partitions and that fdisk
does not work on the PPC port...

So is there a detailed set of instructions on how to do this? I've seen
http://people.freebsd.org/~grehan/iso_install.txt but It's not horribly
detailed. If I do make the change to FreeBSD on a mac mini, it'll be the
only OS and I'd rather not have to boot into the openfirmware everytime I
need to reboot the box.

If anyone has done this and can give me a step-by-step of their experience,
it would be greatly appreciated.

Thanks,
