I recently aquired a few old iBooks. They have 128mb RAM, and ~600MHz.

I am looking for something like Damn Small Linux, that will run comfortably on them. I am currently using Debian, but I am having trouble getting X to run correctly. It starts to load, but ends up stalling, and locking the system up. I tried switching to another runlevel to kill X, but it wouldn't even let me do that. Don't get me wrong, I love the command line, but it would be nice to have browser functionality.

Anyone have any suggestions for a distro that will run on limited hardware, that also supports PowerPC?

Thanks in advance!
