These links may help. You could also check out the Linux and NetBSD ports for PowerPC.

Has anybody done that before. Is any small os available to see. Like ones in osdev rings.

I personaly don't know any small OS's for PowerPC and a quick search of the OS Dev Ring didn't show anything either; but maybe a closer look will show some although I doubt it :\

We have a small page with collected knowledge on the FAQ: http://www.osdev.org/osfaq2/index.php/PowerPC

(most links have already been posted here, though)
