Powerpc development?

What is the status for a powerpc port for haiku?
What would be a good place to start if there is not already one?
How hard will it be, e.g. is there a lot of x86 specific code in haiku?

Thanks for your answer in advance.

Yes, there is a half-way-there PowerPC port, and some work done in preparation for other architectures, but they are all on hold for now, so the developers can focus on getting Haiku/x86 done.
