Which PPC Linux?

I need to pick which distro to put on old Mac hardware…

When it comes to Linux, I’ve mainly used Red Hat on Intel hardware, and on PPC many attempts were made to install LinuxPPC, and that never worked (well, it was 4 years ago) but I have used Yellow Dog successfully…

As much as I have tried to install Debian on PPC, I’ve never managed to get X11 to work, which is ok for a server, but I want a workstation. So, which distro should I try? lists some distros, as does I’m tempted to try Mandrake or Gentoo. I would try SuSE if I could find their PPC distro., but the fact I have to hunt around for it makes it last on my list.

If you’ve got any helpful advice on Linux for PPC, please let me know
