I recall some problems with Linux on PPC. For example, I could never get the line in from the "Screamer" soundcards working, no matter what kernel or ALSA version.
But your thing sounds like it could be an IRQ problem. You might "cat /proc/interrupts" to see where what is going. Also, you might add "pci=noacpi" or even "acpi=off" to your boot arguments in Grub or Lilo, and see of that helps.
good luck, d.
