You are hitting a workaround in the AML code. HP has BIOS' that have
AML with backwards dependencies. \\_PR_.CPU0._PPC is not in scope until
acpicpu runs, but we can't run acpicpu without acpiec. The best part is
that it doesn't need _REG so minus an ugly warning your machine should
be working fine.
