I think the older kernels still supported Apple hardware under the "ppc" arch, but in the more recent kernels it's moved to the "powerpc" arch. > I am currently playing with a 8641D dual core power pc, it is basically > two 7448 processors in one package which is almost identical to the > 7447A, along with peripherals (ethernet/serial/pcie).

If you have followed Linux kernel development and understand the new genirq stuff (and eventually irq threads), or are willing to dig into it, then why not start a brave porting effort and try to, for example, first make your eMac work on newer kernels with adeos/xenomai stuff applied. -- Heikki Lindholm
