@Solarin: Thanks for the post. I also think PowerPC is a little abandoned since Apple moved to Intel processors. AMD64 version of PCBSD would be great. Perhaps PPC processors will be revived with the Cell Processor
@maddog39: i guess you will have to use FreeBSD 7.0 current if you want FreeBSD on your Powerbook G4. it`s not as easy as PCBSD but it`s great once you get it to work like you want.
