install Linux on iMac G5

Is there a Linux distribution, that runs on an old iMac G5 with a PowerPC processor? I would like to use the old iMac as computer for my mother, she would only need an up-to-date browser running, nothing more. I found MintPPC , based on the Debian "testing" branch. Would that work? ---- I am installing mintPPC right now with this installation instruction . It seems to work fine.
