[arch-ports] G5?

I installed Arch on my x86 Desktop and my macbook and i love it. I attempted to install Debian on my G5 PowerMac but had no luck (yaboot problems). What I would like to know is how well does Arch work on a G5, does anyone here use it on a regular basis, and what are the challenges to installing it. Eventually, I would like to stop using OS X.
