linux usb blender live distro on ppc (mac) ?

Hello , I’m teaching using blender to a class of students…
We are on ppc mac machines… that they are actually quite messed up…and I don’t have the autority to format and reinstall everything
So… i was wondering if any of you knows a good linux distro, bootable from an usb key , with blender included that will work on ppc machines…
I use dynebolic on intel machines, and it works good… but i don’t think is compatible with mac…
Please hellllp!
