file mach_kernel
mach_kernel: Mach-O universal binary with 2 architectures
mach_kernel (for architecture i386): Mach-O executable i386
mach_kernel (for architecture ppc): Mach-O executable ppc

Tento system sa da bootnut na PPC aj x86 z jednej instalacie (ak je nainstalovany na disk s APM a nie novsim GPT) :)
Akurat ze xnu este nie je k dispozicii (a nebude do oficialneho releasu), takze funguje len na apple-brand-hw
