Running Mac OS X Natively on Pegasos

Peter writes "The Pegasos is an interesting new platform, being one of the very few affordable non-Apple PowerPC systems. But to be a real alternative for me, I want it to run Mac OS X directly (without the need to use Mac-on-Linux or such). Have any of you Slashdot readers done this, and how much hacking did it take?" The Pegasos currently uses a G3/600, and ships with Debian Linux for PowerPC and MorphOS.
