Great to see Leopard running. Nice work!

I fixed the error by adding CONFIG_MAC_PMU=y to the default config for ppc-softmmu.mak
Builds from your source fix the USB problem in OpenBIOS mainline needing the -device ich9-usb-uhci1,id=newusb -device usb-mouse,bus=newusb.0 to get mouse/kb going in 10.5.
Leopard now has mouse/keyboard working without any specific USB parameters.

I notice the problem in Puma (10.1) It seems there is some timer error?, as e.g., the time remaining for installation fluctuates like crazy (1600 hrs to go), and the beachball spins like mad. At boot there is a too rapid succession of “still waiting for boot device” . Just guessing, but might a timing issue also explain the slowness of Leopard?

Best,
