the dmesg log on the 2.6.30-rc4

On some boxes several processors use the same processor bus id.But they are located in different scope. For example:
        \_SB.SCK0.CPU0
        \_SB.SCK1.CPU0
        As they use the same bus id, OS will complain the OOPS when registering the acpi proc I/F for the processors that use the same bus id.
